WATCH: CNN’s Martin Savidge Dives for Cover from Israeli Airstrike

CNN’s Martin Savidge was reporting from Gaza Sunday when a roof knock and then full airstrike hit a building down the block from his crew, the closest the blasts have gotten to his position. The roof knock is the Israeli warning that a strike is coming, and precedes by anywhere from a few seconds to a few minutes the actual blast. Savidge pointed out that in this case the roof knock was forceful enough to send him diving for cover. He added that if the crew had not already removed the glass from the windows of the room it almost certainly would have shattered.
