Welcome to our viewers in the u. S. And around the world. This is cnn. Im natalie allen. We begin in iraq where isis has again destroyed Cultural Treasures and artifacts during outrage across the globe and iraqi official says the militants bulldozed the site of the ancient syrian city ever nimrud. Some call this a cultural cleansing by isis as they destroy history and heritage. It is a huge loss and tragedy for the whole of humanity and, of course my reaction is one of anger because we do believe that the destruction of heritage, the deliberate i would say, destruction of heritage in iraq becomes part of the warfare and also its part of a strategy of cultural cleansing that exterminates already with the looting of sites, with the persecution of minorities, attacks on people and destroying the incredible Cultural Diversity of iraq and also of its priceless heritage. I think the way they construct their strategy of erasing the culture and heritage is disappointing. Nimruds culture is the latest to be destroyed. The tomb of joan a was destroyed in a bombing last year. The great mosque of aleppo, once one of the oldest reduced to rubble in 2013. Insurgents bombed the great mosque of samara in 2005 and in 2001 the giant buddhist in afghanistan more than 1500 years old were destroyed in explosions set by the taliban. Of course its not just historical relics but hundreds of thousands of innocent civilians who could be caught in the cross hairs of isis. 350,000 people in the syrian city of deir ezsor. Across the border youll see some progress in defeating isis. Iaqi supporters captured a town on the outskirts of tikrit. They can cleared isis from the town of al baghdadi. Thats critical because its near a key base where u. S. Marines are training iraqi troops. Iraqi forces drove isis from several villages south of al baghdadi baghdadi. All of this while the u. S. Is keeping an eye on iran in iraq. Iraqs military reliance is making some leaders quite nervous. Reporter the latest u. S. Military assessment, most of the fighters here are iranian backed shia militia with iranian weapons fighting to reclaim the city of tikrit. Irans farsi language heard here and field commanders look at their plan. Iran watching them happy to have the iranians do the bulk of the Ground Fighting but worried again it could open up a cauldron of shia versus the sunni violence. For the sunni and shia sectarianism that has happened for years, it could be strategically disastrous. Reporter they worry the government could become a tragic country of iran. The risk is that it all falls into iranian hands. In terms of ensuring that our resources dont migrate over to shia militia, theres no easy way to be absolutely certain that that cant happen. Reporter the u. S. Wants iraqs Prime Minister to guarantee a government and military with sunni representation vital to stopping sunni support for isis. Abani just announcing his Security Forces east of fallujah and west of ramadi are launching new operations in the sunni heartland. Iraqs reliance on iran apparently working in eldur south of tikrit which baghdad says has been liberated. A potential u. S. Victory of sorts. Theyre advising the military. Theyve been liberated according to the coalition. Dont count on the u. S. Joining forces with iran. There is no cooperation between us and the iranian forces. Were going to have to count on the Iraqi Government to do those things necessary to number one, ensure that things dont trend towards greater sectarian violence. Reporter there may not be formal cooperation with iran but a senior u. S. Military official tells me that when Coalition War planes arent in the skies, when they are flying the Bombing Missions the u. S. Tells the iraqis where the planes are and relies on the iraqis to tell the iranians to stay away. Barbara starr, cnn, the pentagon. Westerners were apparently the target at a shooting in mali that left at least five people dead. Two people are under arrest. It happened in the capitol at a nightclub that is popular with people from the west. One witness tells cnn the shooters were targeting foreigners specifically caucasians. One french citizen, one belgian, and three people from mali are among the dead. A Police Officer and a guard were killed in the street as the attackers left. A bomb in egypts now delta region has left one person dead according to Egyptian State media, 11 others are wounded in that blast which happened outside of a bank. The person killed was a police sergeant. Theres no word yet on who might be responsible. An american missionary is now free after being captured in central nigeria nearly two weeks ago. Phyllis sortor was captured where boko haram does not operate. They wanted a ransom of more than 300,000. U. S. Officials wont comment on the release but say negotiations were involved. Well it still seems impossible that a plane carrying 239 people vanished, but it did. And its been a year since mh 370 disappeared and what happened to it remains a complete mystery. As Suzanne Malveaux reports, the search goes on. Reporter one year later and still nothing. The search team still insists the debris field is here on the ocean floor, a location they say satellite data reports to. Above the Water Surface search crews are still weathering cyclones and 50 foot waves. Below, mountains, trenches volcanos make up the treacherous terrain. 40 of the priority search zone has been covered but no wreckage recovered. And with no real clues as to what happened to the boeing 777 after it lost radar contact an hour into the flight which took off from kuala lumpur theories abound. A recent New York Times report cites the rogue pilot option. They think that the pilot and copilot intentionally took the plane off course. There is no evidence that either had motive to do so. The chief of the Malaysian Airlines says they had no reason. The captain is a very capable man. The sister urged people to stop blaming her brother. She said as things stand today, with no tangible evidence none of you have any right to blame captain shah for any wrongdoing. As an average student in school he would not have been able to master mind such a plot. Nobody knows why the plane lost contact. Some theorize there could have been a massive electrical problem, a cockpit fire or a cabin fire turning it into a ghost plane. Why isnt hasnt shown up yet, that is the true mystery of it. If it had crashed in the way we think it did, to hit the water and break up into pieces there would be pieces somewhere. Aviation analyst jeff wise carried on his own theory. Russian operatives who took the plane. None of these theories can be proven or disproven until some shred of the plane is found. Even then we may never know exactly what happened. The families of those on board the plane still wait in agony for any news about their loved ones. To remember the passengers and crew a cantle light vigil was held on kuala lumpur. At least one woman is holding out hope her husband is still coming home. Translator this year has been very painful. I dont know what happened. For me this is a torture. Its changed our life a lot. I hope the plane will appear soon that my husband will come back soon. Now that were in malaysia we also hope the malaysian government can meet us instead of avoiding us. We remember those days and those days are still here one year later. Lets go down to anna coren. Shes live in kuala lumpur. Certainly you have talked to so many of these families in the past year youve covered the search anna. Certainly understand that theyre holding out hope. They just want to because they just dont have any answers. That woman is certainly not alone, is she . Reporter no, absolutely not natalie. I think she puts it very well. This is torture. It has been torture for all the families of the 239 people on board mh 370. We are now hearing from some of those families that they are angry that this interim report which will be released by the malaysians tomorrow is, in fact going to be released on the day of the anniversary, the one Year Anniversary since the boeing 777 vanished off the radar. They say that its insensitive, that they could have picked another day. Now this interim report is expected to be a technical investigation. Its made up of an international committee. On that committee were talking about australia, the United States the u. K. China, france singapore as well as boeing rolls royce. So certainly a lot of bodies involved in this report which is expected to have 600 pages. We had heard from the malaysian government that the families are going to receive that report before it is made public but as i say, hearing from those families today, they are furious that it is being released on the same day of the anniversary. They say they could have picked another time to release this information. We certainly caught up with the transport minister and asked him with the overwhelming criticism about the way that malaysia has handled this crisis in particular with the families. They feel like a nuisance. The media has known before they have been informed. Take a listen to what he has to say. These are such details. This report come to us and specify all the objects that are under sea base so i think that to say that we didnt give details, not true. I think we should further engage them. Youre saying you should further engage them. Has not enough been done . You see, its not that. If they feel that they are not given enough then we will do more. Reporter yeah malaysians saying there have been Lessons Learned in this tragedy. Certainly they have improved their protocols as far as security goes. Remember that there were two passengers on board, two iranian passengers that were holding false passports. They will also improve their flight tracking system which, of course extremely important considering the plane vanished from the radar, natalie. All right. Anna coren, thank you from kuala lumpur.

Police attacked them with night sticks whips and even a rubber hose wrapped in barbed. That day lives infamously as bloody sunday. President obama and 100 members of congress will be in selma for the anniversary. John lewis had his skull fractured that day. Athena jones has his story. The bridge of selma is almost a holy place. It is a place where people gave a little blood to redeem the soul of america. In this city people couldnt register to vote simply because of the color of their skin so they had to change that. Reporter john lewis, who has spent almost three decades in congress,s was just 25 years ago. I can never forget what it felt like to be in that experience on bloody sunday. We came to the highest point. Down below we saw a sea of blue. Alabama state troopers and behind the state troopers we saw men on horseback so when we got within hearing distance of the state troopers youre ordered to disperse go home or go to your church. The major said, troopers advance. I thought over and over again, they going to arrest us. They came clubbing us beating us with night sticks trampling us with horses. I went down on my knees. My legs went out from under me. I thought i was going to die. Reporter he was carried back to the church where the march had begun. It was there he issued a challenge to president lyndon johnson. I stood up and said i dont understand how president johnson can send troops to vietnam but cannot send troops to selma, alabama alabama. Reporter after bloody sunday president johnson spoke to congress. It is wrong, deadly wrong, to deny any of your fellow americans the right to vote in this country. Its not just negros but really its all of us who must overcome the crippling legacy of bigotry and injustice, and we shall overcome. He was the First American president to use the theme song. I looked at dr. King tears came down his face. I started crying. I didnt like to cry in front of people but i cried. President johnson federalized Alabama National law, called out parts of the United States military to protect us all the way from selma to montgomery. Reporter on august 6th president johnson signed a landmark Voting Rights act ensuring that all citizens could vote regardless of their color. It was bloody sunday that helped make that day possible. Its also why lewis returns to this bridge every year. The vote is powerful. It is the most power full nonviolent tool we have in our Democratic Society and i dont want people to forget that people paid a price. Reporter athena jones, cnn, selma, alabama. What a story and a remembrance. Cnn will mark the 50th anniversary of the march on selma with live coverage throughout the day. Be sure to stay with us for much more on the historic day.

Scientists believe about 4 billion years ago an ancient ocean on mars held the same amount of water as earths arctic ocean. Cnns adam dunaghy looks at how instruments on the surface helped find these lost oceans. Reporter mars 2015 a planet of rock and red dust. But it wasnt always like this. Ridges like these in the martian hint that water once flowed here but was once a mystery until now. According to new research from nasa this is mars around 4. 5 billion years ago, a planet with a vast ocean covering nearly 20 of its surface and as deep as the mediterranean. Mapping the waters of mars required data from the red planet itself and even some from right here on earth. Its a collection of knowledge of meet logic records, spacecraft and ground bases that have allowed us to get a nice picture of how water evolved on the planet. Reporter key to the discovery were measurements of this rare form of water. It contains a heavier form of hydrogen which prevents it from leaving the Martian Atmosphere and being blown into space. The higher concentration allowed scientists to concentrate how much more water the planet had. Current estimates show only 13 of the original martian water remains on the planet with most stored as polar ice caps. The rest like much of marss atmosphere was slowly lost. As well as adding a splash of blue to the red planet this new data bolsters the idea that mars may have teamed with life. Ultimately we can conclude the idea of an ocean covering 20 of the planet which shows habit habitability. Reporter it will finally tell us if there was once life on mars, one of the many mysteries that the planet still holds. Cnn, london. Fascinating. Derek van dam joins us because he covers earth but, oh, my goodness wouldnt you want to cover mars too . Look how fascinating what were learning. Yeah it is. All that research up there by nasa is so crit
