GAZA CITY (CNN) -- CNN's Anderson Cooper got a scare today while preparing to go live in Gaza City.
Watch here and you can see an explosion behind him. Cooper says the blast came after an Israeli airstrike hit a building housing the offices of media organization affiliated with Islamic Jihad.
Israel says it's targeting places that have what it calls terrorist activity.
It began its airstrikes last week in response to the high number of rockets fired at Israel over the past year.
