"Whoa!" Bomb falls during Anderson Cooper live CNN broadcast.

Anderson Cooper was caught off guard Sunday night during a live broadcast from Gaza when a bomb exploded in the background during his news report. While Cooper did not know exactly where the bomb went off, he noted that many car alarms were set off in the vicinity. Always the model of professionalism, Cooper recovered quickly from his initial shock and filled viewers in on the danger of the situation.

“That was probably the largest explosion that we’ve heard just in the past hour– there have been a number of explosions in the past hour or two, but that one was pretty loud,” he said.

Cooper was discussing the most recently reported fatalities as a result of the escalating conflict in the Gaza region when a bright light caused from the explosion is seen in the background followed by the thunderous bang seconds later.  Cooper ducked instinctively and uttered a “Whoa!” before composing himself almost without missing a beat.

Fatalities in the region have so far climbed to 87 Palestinians and 3 Israelis. "There's a lot of fear," Cooper says. "People are bone-tired. You know, this has been going on for days now. There's this constant sound of the drones. It is a very eerie feeling. It's a very strange feeling."
