Moving to the middle east where hundreds of gaza residents are fleeing their homes after israel dropped leaflets in northern gaza today warning residents to move away from hamas sites to avoid air strikes. It helped 150 u. S. Citizens leave gaza and get into jordan today. Israel says its already hit what it calls more than a thousand terror targets. Yet rockets from gaza keep coming. The Gaza Health Ministry says 368 have died and most are civilians. Ben wedeman spoke to people as they tried to get their families to safety after the warnings from israel. Reporter the clock is ticking. Its time to go. Israel ordered the inhabitants of this area in northern gaza to leave by 2 00 p. M. Sunday. Hamas told them to stay put. I dont answer to them says ahmed. I do whats best for us. Hes sending his family to safer ground in gaza city, relatively safer, that is, although hell stay behind. Luckily he caught a taxi to take them away and not a moment too soon. These children have heard the crash of shelling and air strikes for days now. But it still tafs them. This is the third time in the last five years ahmeds family has had to flee their home. Like almost everybody in this area were leaving, too. Its dangerous. Theres some people staying behind to basically guard their houses. But as the man back there told me, 80 of the people in this area have already left and at this time the deadline to leave ends in 35 minutes. On the drive into gaza city, empty streets and rubble from the israeli air strikes. By taxi or mostly by foot, the people fleeing the north are heading to United Nations schools, more than a thousand in this school alone. Food has yet to be provided. The only source of sustenance, a water tanker. This family of 15 fled their home at 2 00 in the morning. We told the kids, get up, get up. We walked all the way here. This baby needs milk, but we dont have any. We have nothing, not even safety. Theres little to do here but wait until the fighting stops and they can go back to their homes. If theyre still there. Ben wedeman, cnn, gaza city. On the israeli side of the border people are also fleeing the conflict. Diana magnate has this story. Reporter kibbutz is 880 meters from the fence. The explosions rip through the evening airs. The deep thud of an israeli air strike. The shorter crack of outgoing fire and the hiss as a missile streaks past us. We just heard a rocket go very, very close over our heads. These playgrounds arent full of children any more. Theyve all moved to a kibbutz in northern israel hoping it will be safer there. Though just friday morning a rocket came in into the north from lebanon. The people tell me theyre not just scared of rockets. Theyre scared of militants from gaza tunneling in. This man runs the security. Now that operation protective edge is under way, he carries a gun. He has a dim view of hamas. Unfortunately here hamas, the civilians, they hide behind the civilians. Here is a soldier on the front. And all the civilians in the shelters. And the other side, the civilians outside and hamas inside the shelters. It turns the out what we heard was an antitank missile. It had hit a military jeep in the base next door injuring two soldiers. Israeli tanks fired back, but the rockets from gaza keep coming. Reporter you can hear another one of the red alerts. There was a mortar that came over yesterday and hit that building. This is the moment where you look for the nearest shelter and get inside it. Each house has its own shelter. This is our own shelter. She says shell spend the night in her safe room. Her husband and daughter all tucked up there together. Theyre sorry its come to this. We used to have a Good Relationship with them. We had friends in gaza who were even at my wedding. And we used to go into gaza an saturdays and eat humus and sit down at the beach. Most of the people there want this. Reporter but now the call from the leadership on both sides seems more like a battle cry even as the people pray for their liveses to go back to normal. Diana magnate, cnn. Israels iron dome Defense System has been credited with keeping civilians there safe. In a minute, well show you how it works.

Its an ominous sign of more strikes in the future. Earlier today israeli troops went into gaza to raid a missile launching site. Wolf blitzer got the details from a spokesman for the Israel Defense forces. We utilize our special forces in order to do special missions. The site that we attacked is deeply involved with the longrange rockets that have been showering tel aviv, showerishowe showering north of tel aviv, showering jerusalem. So we thought it was necessary to utilize special forces to carry out a special mission. Indeed, they made their mission. They were able to succeed in their mission. There was impact and the conflict with terrorists there on the site. We have few scratches and grazes but nothing substantial. On the israeli side. Palestinians we had air support on site as well and the palestinian terrorists, they paid a heavier price. Was this an isolated incident or will there be more israeli, as they say, boots on the ground . We can expect these type of activities taking place. The ops that happen below the radar, in and out, swift missions, quickly, concise and very precise at what theyre doing to get that added value to safeguard. So there will be more of these operations. What about tanks, armored personnel carriers, formal invasion of gaza as has occurred in the past . Were explored that possibility. But in the last five or six days we have brought up the forces. Indeed theres a substantial force on the border with gaza. If the order is dpichb, were prepared for that type of activity. Was that the reason youre leafletting and telling folks to get out. Theres a half million people, its almost impossible that theyll all be able to escape. Whats your goal here . The area that weve announced that people should leave is a lot smaller than that about the town of beit laeha. That is a main staging point for rockets against israel. Theres a lot of hamas deeply invested in that. Its some energetic palestinian commander on the ground there that thinks he can launch rockets at israel freely. We have to deal with that problem. Thats why were suggesting for their own good, keep away from ham hamas, move out of that town because we intend to target it. The italians, elderly, young, they wont be able to leave. We hope theyll abide by our advice. Its an absolute necessity. The terrorists launching rockets from beit laheya are at risk. We announced our intentions to do so late last night. Theres a timeline. Unfortunately, due to the operational concerns, i cant point at the specific hour, but indeed we expect the people to leave. Within hours, can we say that . I would say so, yes. When you go into that be beit laheya areas, tanks, from the sea, a limited commando operation or a much more robust military operation . Well have to leave that for the operation itself. There are growing fears israel and hamas are edging toward an allout war. According to the Israeli Military more than a hundred rockets have been fired in the past week. Nearly 150 of those have been intercepted by israels sophisticated system called the iron dome. How does it work . Heres cnns tom foreman. Reporter just as hamas has improved the range of the rockets its firing into israel, israel has improved the performance of its iron dome missile Defense System. So much so that israeli authorities are claiming 90 success in neutralizing the threat from missiles from gaza and those aimed at tel aviv and haifa. How does sth work . The first phase is detection. Any time rockets rise up and head toward israel, high tech cameras and Radar Systems and computers start looking at them, figuring out how big they are, how fast theyre moving and importantly where they are headed. Because simultaneously, the analysis and targeting phase is entered here. That means if these are headed off into the sea or into rural areas where they wont hit anything, they just let them go. They dont care. Let them fall to the ground, but if they spot one of them headed toward buildings or a city where people would likely be hurt. Then the destruction phase is key. That means that these computers and Radar Systems reach out to batteries of missiles on the ground in israel and they launch them automatically sending these missiles out here that are each about ten feet long racing toward the incoming threat. Each one of the defensive missiles has 24 pounds of high explosive on them. When they get close enough, they blow up, obliterating everything in that air space. This is not cheap. This system was originally developed by an Israeli Defense company, but the United States has kicked in 235 million to expand the iron dome. By the way, each of these costs about 62,000. But the goal here for both israel and the United States is to make the system even better at intercepting bigger missiles further away at higher altitudes. You know what thats all about. Thats making sure that maybe this system can become a Defense System for both countries against more robust enemies in the world. Thanks so much, tom.

Reporter did you think you should have said Something Different . Or acted differently . Yeah, act different. Reporter you think the jurors didnt take you seriously . Yes. They judge how they talk, how they look, how they dress. Reporter and they were judging you . Yes. Reporter and that was the beginning of an astonishing turnaround in Rachel Jeantels life. What sort of issues did she have to deal with . Posttraumatic stress. She was suffering from posttraumatic stress. Reporter ron vereen is a miami attorney who organized a support group called the village providing rachel with counseling to deal with the grief of losing her friend and intense tutoring to overcome problems in school. No one knew it at the time but when 19yearold rachel took the stand she was barely able to read and write beyond the level of a third grader. She pushed back. I saw what happened when somebody gets on your bad side. I dont know if i would ever want to be on your bad side. No, you dont want to cross. Reporter but her tutors didnt give up and neither did rachel. These photos taken in may marked the moment their work paid off. Rachel donned a cap and gown and collected her high school diploma. She credits what has taken place since what happened in the courtroom to Trayvon Martin, all the good things. The fact that shes graduated, she said i kept my word to trayvon that i would do this. Reporter shes also keeping a promise to herself, by having the last word for people who criticized the way she talked and acted on the witness stand. Theyre implying that youre not very smart. Yeah. You cant say that. You cant judge a book by a cover. Reporter shes had to do a lot of growing up and learning how to take responsibility for her actions. Rachel jeantel says she believes George Zimmerman should do the same. What do you say to George Zimmerman right now . He know he did wrong and you got to admit up to it. To me youre not a man. George zimmerman, youre not a man. Thats still a little boy. Reporter we attempted to contact George Zimmerman through his attorneys but theres no reply. Rachel jeantel still has a
