Hamass rog et rocket attacks. We show you what it means for those caught in the crossfire. It is saturday morning in ukraine and gaza. Two volatile regions separate by 1,100 miles. You are locking at video of the crash flight of Malaysian Airlines flight 17, and live images of gaza city where the death toll is rising again. Well get to that in a moment and well begin with that. Pictures that remind us of how much was lost. Here you see some of them lined up. A picture, a surreal one of a minor searching in a sunflower watch. And then scattered in the grass a notebook with a drawing, playing cards. 298 people were killed. The investigation takes on new urgency and anger. Scott heidler was one of the first journalists to arrive at the crash site. Here is his latest report. As the sun rose it revealed the scope of how difficult the recovery and investigation will be for flight mh17. The debris is a vast area around the wheat fields, a circumference of 10km. There was an explosion in the sky above the house. I came out to see what happened. The plane fell in many pieceses as it fell, it broke apart, all the pieces fell in the sky. Reporter emergency workers began the task marking the bodies and parts. The markers dot the scorched landscape. As the rescue workers fanned out across the fields identifying the human remains, we were close though this debris field when some came up. We overheard one say to the other, he said theres too many bod yois on there, i dont have enough stakes or flags. Before working their shifts, mibors from a coal miners from a coal plant came to help. We came, its a tragedy. We want to find out what happened and stop people thinking they are terrorists. A few hours after the crash leaders of a prorussian separatists were on the site. Now, unfortunately, people from other countries bament the victims became the victims in this nondeclared war. The ukranian Prime Minister reached out to families of those killed, and placed blame. Everyone is to be accountable and responsible. I mean everyone who supports the terrorists. Including russian frags and russian black federation and russian rageam. To accurately determine who is behind the attack on civilians, International Investigators need to get in. Both establish a corridor through a battlefield to allow that. The investigation into the deadly rash is a joint international effort, a job made difficult because its in a combat zone. Lisa stark has more. The first outside observers made it to the crash site on friday. Monitors from the organization for security and cooperation in europe helicoptered into the area and drove to the debris fields. They were not able to move around freely. They had limited access and left after 75 minutes, calling the need for unfettered access important, in our view. The observers will try again on saturday. Theres a lot of dire and eager innocence to get experts and emergency workers here to start caring for the bodies. Safe access to the site is critical. Investigators from the fbi are heading to ukraine to assist in the probe. They are going no further that kiev as of now, worried about security. In the rebel held areas. The missile that brought down the plane was fired from inside ukraine, from an area controlled by russian separatists. At the pentagon they are pointing fingers at the russians themselves. The missile itself, the fa 11, the sa 11, the one we believe was used is a sophisticated piece of technology. It strains credulity to think that it could be used by separatists without some measure of russian support. Theres no firstly information on whether either of the planes two black boxes have been recovered. Independent investigators will want to find them. The other priority, identifying the remains of those that host their lives and returning those remains. Under the law ukraine would head up the investigation the obama investigation is stressing the need for a credible investigation. The hope is that icao, the International Civil organization based in canada would play a leading role. Ukraine agreed to offers of help from a host of groups and countries, including the u. S. , malaysia and the netherlands. All of that means little if investigators cant get the proper access on the ground. President obama commented on the internet today saying what happened to flight 17 should be a wakeup call to the world. The u. S. Says it convinced a russianmade missile fired and shot the American Airline are out of the sky. Mike viqueira reports. The white house says it will await the results of an international and impartial investigation. On friday president obama walked to the edge of casting blame. His Administration Says it has not reached the final judgment. President obama left little doubt about who he thinks is responsible. Evidence indicates that the plane was shut down by surface to air missile launched from app area celled by russian backed separatists in ukraine. The president laid out the evidence. Russianbacked separatists shot a ukraine transport plane and helicopter, and claimed shooting down a fighter shet. We know that they are heavily armed and trained and we know that that is not an accident. It is happening because of russian support. Warning of miscommunication and tampering with evidence. The president called for a ceasefire, to allow safe and rapid access to the crash site. As president obama cast suspicion on the separatist and russia, officials insist theyll wait for a verdict from international crash experts. Our focus is seeing a thorough investigation. U. S. Officials believe investigators, if given access to all the evidence will implicate the separatist and their sponsors. A resolve that will strengthen europe oops. This will be a wake up call for europe and the world that there are consequences to an escalating conflict in Eastern Ukraine. Speaking of european resolve. President obama spoke to Angela Merkel, and david cameron. They spoke of a need to maintain the integrity of a crash site, forwarding a cover up. They talked about sanctions against Vladimir Putin and russia. Mike viqueira at the white house. Here is a look at the radar monitoring flights, taken within of the hour. No planes are flying over Eastern Ukraine. Many have been avoiding the region. British airways, Korean Airlines and quantity along those. The jet was on his way to amsterdam. This is the second time in four months. Malaysia airlines is facing anger and demands. Florence louie is in kuala lumpur. The malaysian Prime Minister, in his second statement on the crash of mh17 used strong words calling it inhumane irresponsible. He said malaysia are not interested in assigning blame, but they want to condemn the violent senseless act and the countrys flags will fly at half mast as a sign of warning for those on board the flight. Now, the transport minister earlier on friday had to field tough questions about why Malaysia Airlines was flying the route, despite the fact that some aviation body deemed it risky and advised airlines not to take the flight path. Malaysian airlines responded by saying it was an approved flight path and other airlines, 15 out of 16 counties in the association of Asia Pacific Airlines used the route. We have to look at what impact this will have on Malaysia Airlines, the national carrier. This is the second major aviation did asker for the aircraft following the disappearance of flight mh17. We are learning more about the passengers. 298 died in the crash. Bts has some of their Jonathan Betz has some of their stories. Nearly 300 were on board the flight. Most from the netherlands, nearly 200 passengers, including aid reachers, a nun and families going on fake vasion. The final moments before the plane took off. No one could have expect what followed. Candles flickered. Memorials crew as we put faces to 298 lost. Among the stories, an australian tomb returning home. Mum and dad, we love you. Well miss you so much. They wanted to see the granddaughter walking when they came home. Most of the passengers were dutch, including carr line, a student and rower. She was positive and willing and hardworking. The only american was quinn. 19, he was a citizen of the u. S. And netherlands. Travelling to meet his family. The president spoke about him. Quinn luce ag shansman was killed. Our thoughts and prayers are with his family. At the World Health Organization a moment of slps. Glen thomas was amongst a few heading to conference in melbourne for aides. What if the cure for aids was on the plan. We dont know. Theres Prime Minister incident researchers doing this for a long time. Theres the families on vacation. People like this woman, about to visit her 86yearold mother. And this grandfather takes his children back home. They said goodbye to the grandparents, and headed back to school. And for one australian family, they lost family on the Malaysian Airlines flight that disappeared. Yesterday she found her stepdaughter and stepsop was on the night. And those that avoided tragedy. We were supposed to be on the flight. They didnt board, 298 others did. Across the globe families are important apart, facing an assistanceless sorrow. 80 children were among the dead, an indication of how many families were on the flight. As you heard, the leading h. I. V. Aids researchers kld were on their way to a conference in australia. Courtney kealy has that part of the story. Id hike to call for a minute of silence. The World Health Organization confirmed the death of a spokesman, killed aboard the plane, shot out of sky. It is with deep sadness that we have to inform you that who lost one of our colleagues. Thomas is one of several killed while on route. Social media shared reports that possibility as map as 100 as many as 100 scientists, distress and researchers and members of the ad community may have been on the flight. The tributes lit up. It read the conference will go ahead. President obama paid condolences. In this world today we shouldnt forget in the midst of conflict and killing, there are people like these, people focussed on what could be built, rather than destroyed. It was put into words earlier i spoke with dr rachel breeman, an h. I. V. Research are and a professor of pead attics. I asked her what the loss of renowned aids researcher means to the community. Dr langers loss is significant. As a scientist and advocate, he spearheaded efforts to provide h. I. V. Treatment in the worlds poorest places. In particular his research revolutionized how we prevent h. I. V. Infections in babies. He was concerned on how to take care of children. His work was to change the cores of an ability to have app aidsfree generation. What does this mean for aids research . We are a community used to mourning losses. Many of us are in the fight because of the 33 Million People at risk of losing their lives at h. I. V. We have lost patients, colleagues and friends. We think well be cata leased by these losses, to weres forward and do the work that they were strong advocates for. Well look at the International Aid conference. Sunday, 8 30pm. Here on al jazeera. The streets of gaza during an israeli invasion. Nick schifrin is on the ground. He shows us what life is like in a war zone. An emotional toll. What the u. S. Is doing for vulnerable palestinians. Youre looking at live pictures of gaza city. Its early morning, day three of a ground offensive. Israeli Officials Say the invasion could expand and last two weeks. So far u. S. Rail says israel says it hit more than 200 targets and found for than 20 tunnel entry points. Two israel yits died. 370 israelis died. 370 palestinians. And 73 of the victims have been children. Nick schifrin reports tonight from gaza. And hes been reporting since the israeli invasion began. He talks about the Human Element of people of gaza in the war zone. The violence is close, flying in above you head. There may be a ground war, but most strikes are fired from the air. The tart a television station fired from hamas. Hit by israeli missiles three times in five minutes. Other targets are peoples homes. This family was given a 2 minute warning. His home was pulverized by an air strike. Everyone survived, thanks to the warning. His children are terrified. The big sister tries to console her little brother, to no avail. To find an escape kids try to be kids. In gaza they play the beautiful game in enclosed mezzanine. Open spaces are too dangerous. This 12yearold doesnt like sacer, but he needed to get out of the house. For more than a week the family keeps them upstairs, inside, because of air strikes. When you get scared what do you do. Stay in my house and dont move. When theres a bomb or an attack. He is scared. Abduls favourite distraction from the booms. His cannes un, a Traditional Middle Eastern harp. It soothes him through a third war in six years. Id like to live in peace. And to try to live with a little security he sleeps in the hallway hoping form is more peaceful than today. For those children living in gaza the toll is immeasurable. The relief and Emergency Agency helps those displaced by the conflict. The director of operations, robin turner, talks about the most vulnerable. As we have seen for the last 10 days, streets are empty, shops closed. 43 schools are sheltering displaced. We have between 45 and 50,000 people sheltering in the schools. For the population, its terrifying. The air strike comes without warning. Gaza is 150 square mile. Theres if 1. 8 Million People here, and they cant leave. When we say the displaced are coming to the school, they are moving a mile. Its not like you are in washington d. C. , and somebody is going to attack it so you go to West Virginia and nebraska, this is your third war if you are a 6yearold child. Im not seeing injured children, i see children acting like children. It manifests in behavioural ways impacting the ability to learn. Theres damage to water. Hundreds of thousands of people are without Running Water and damage to infrastructure. In the best of times, gaza has power. You can imagine what its like now. If they are far away you hear them. If they are closer then you feel them. Try to avoid getting caught up in the statistics. Whether there has been 45, 50, 60 killed, whatever the numbers in, they are lives that will not be lived. Experiences that will not be had. They are young people with the same rite to life as anybody else. We need to remember this is a human story. While the displaced want a ceasefire, nothing will change unless the conditions in gaza improvements. Israels ground all the into gaz e, what will it take. I speak to two gs guests. And u. S. Intelligence used to try to figure out what happened to flight 217. Welcome back to al Jazeera America. Im John Seigenthaler in new york. Coming up, hunting for hamas, israel troops on the ground in gaza, rooting out tunnels and destroying equipment. Russia reacting. The kremlin blaming ukraine for the flight 17 disaster. A report from moscow. And the rebel commander, a mysterious man leading prorussian separatists and his connection to the airline crash. Israel says operation protective edge is aimed at desmantli desmantling hamass military ability. The israeli sought on gaza pressed forward as rocket attacks come out of gaza. The stated objective of the Israeli Campaign is to launch a Ground Invasion stopping the ability of hamas to launch rockets out of gaza, and to target the tunnels allowing palestinians to infiltrate the israeli side of the border to allegedly sneak rocket parts and other weapons across the egyptian border, and tunnels allowing leaders and some weapons to be hidden under ground. The israeli Prime MinisterBinyamin Netanyahu had a Cabinet Meeting in which he was authorised to accelerate the ground campaign. The Israeli Military of staff said the campaign will accelerate. But both lowered expectations and Binyamin Netanyahu said there was no guarantee that this will be 100 successful. He went on to ta the other options, a ceasefire negotiation. Without action the cries would be higher. He went on to say there are facts he kont reveem to the he cannot reveal to the public. Some Officials Say tunnels have been found and could take days to exploit. All of this contributes to how the israeli army are taking a measured approach at going into gaza. There are not israeli troops in gaza city. They remained in the north and south. How the Campaign Conditions is left to be seen. It is conceivable that we wont see air strikes, but possibly israeli troops there as well. Ambassador pinkers is in tel aviv. He joins us. Ambassador. Let me start with this question. The death toll has risen 300. A large portion is civilian casualties. We heard from the israelis, they wanted to minimise civilian deaths. No, i dont think they failed. I think as the correspondent, as your correspondent reported a moment ago, its a measure of operations. Until now, theres not been open battles between hamas and Israeli Defense forces, and there has been a very concerted effort to avoid engagement. What you see is casualties, the tragic loss and the tragic killing of children, is that population centers, where hamas uses the civilian population as human shields as israel and egypt indicated. They were Aerial Bombardments and mess isles in drones that have been launched previous or proceeding the ground operation which i emphasise is limited at this point. Why do they continue to fire into the are
