TODAY | November 17, 2012
>>> want to begin this half-hour with the tense situation going on in the middle east . hamas and israel exchange fire overnight. the israeli military has now massed tanks and troops along the border with gaza , signaling a ground invasion could be imminent. richard engel is in gaza . richard, what's happening there this morning?
>> reporter: good morning. israel has also sent troops and military hardware to the border here in gaza . inside gaza city , there have been more air strikes . in fact, there was an air strike here not long ago. we can hear israeli drones in the sky, as this conflict continues to escalate. gaza 's skyline last night, as israel launched more than 200 air strikes to destroy hamas rockets and punish the hamas government and perhaps prepare the ground for an invasion that could become a blood bath . but hamas was still able to fire back, launching rockets into southern israel . many of them were intercepted by israel 's iron dome defense system. in gaza city , there is no real air defense , and the hamas prime minister won't be meeting any more officials in his office. yesterday, he greeted egypt's prime minister here. today, the tunisian foreign minister's delegation could only look at the rubble. witnesses say the prime minister's office was hit by at least four israeli air strikes . this was the symbol of hamas 's authority in the gaza strip . now hamas 's top leaders have gone into hiding. so israel is hunting them down in their homes. israel flattened this apartment building where a hamas police official was living. amazingly, the 35 residents inside escaped as the building pancaked. but next door, a middle schoolteacher who says he isn't involved with hamas , told me his five children are now in the hospital.
>> translator: the israelis aren't being precise. i didn't launch any rockets at tel aviv . there is no excuse.
>> reporter: residents salvaged what they could. so did this 4-year-old. these are childhood memories she's unlike tloi forget. in most of gaza , the streets are closed. men steeled their nerves, watching nonstop hamas videos now on tv that praise the militants. gazans know they can expect more destruction and more deaths. several middle east leaders, including the turkish prime minister , are meeting today in cairo, but so far, there is no real talk of a cease fire . lester?
>> we can hear those drones behind you. what just happened there, richard?
>> reporter: it sounds like a rocket was just launched coming out of some part of here in gaza city heading in the direction of israel . it will take a couple of minutes before it lands. it's heading in the direction of what appears to be a city that was hit by similar rockets earlier today, and according to the israeli media , three israelis were lightly injured in that attack. we'll know what the result is of this quite soon.
>> okay. we just heard that. thank you, richard engel , appreciate
