Palestinians officials: Bloodiest 24 hours yet in Gaza

Israel investigating Gaza bombing with civilian casualties
Throughout the night and into the day, the Israeli military pounded the Gaza Strip in a bombardment that came by air and by sea. Charlie D'Agata reports the air strikes are aimed at crippling Hamas and its ability to fire missiles into Israel.

(CBS News) Despite efforts towards a cease-fire between Israel and Hamas, Israeli fighters jets continued their aggressive airstrike campaign on Tuesday night, as naval warships supplemented the air attacks, firing dozens of rounds into Gaza.

Palestinian officials told CBS News' Charlie D'Agata that the past 24 hours have been the bloodiest yet in the weeklong fight. One airstrike leveled a Gaza City block, taking out the Interior Ministry building. The Israeli military have called the ministry building a commanding control center for Hamas, thereby making it a legitimate target for the attack, but Palestinians continue to suffer widespread civilian casualties. Palestinian officials say more than 140 people have been killed, and 1,000 wounded.

Another blast landed in a soccer field in a neighborhood of apartment buildings and hotels, and rattled the hotel where many foreign journalists -- including a CBS News crew -- were staying. D'Agata called the strike, "a close up example of the barrage of attacks that have come by land, air, and sea," and described the ongoing attacks as "sustained and relentless."

And, after a bomb exploded on an Israeli bus near the entrance to Israel's defense headquarters in Tel Aviv on Wednesday, there is a growing concern in Gaza about the threat of retaliatory attacks. Hamas has not claimed responsibility for the attack but a Hamas spokesperson said, "Hamas blesses the attack."
