A Palestinian policeman reacts as rescue workers search for victims under the rubble of a house, which witnesses said was destroyed in an Israeli air strike that killed three senior Hamas military commanders, in Rafah in the southern Gaza Strip August 21, 2014. An Israeli air strike killed three senior Hamas military commanders in the Gaza Strip on Thursday, the Islamist group said, the clearest sign yet Israel is focusing its assault on those leading attacks from the Palestinian enclave. The Israeli military had no immediate comment on what would constitute the killing of the most senior Hamas men since it launched its offensive on Gaza six week ago with the declared aim of curbing rocket fire into its territory.

A streak of light is seen as a rocket is launched from the northern Gaza Strip towards Israel August 21, 2014. Israel killed three senior Hamas commanders in an air strike on the Gaza Strip on Thursday, the clearest signal yet that Israel is intent on eliminating the group's military leadership after a failed attempt on the life of its top commander this week. After six weeks of conflict in which more than 2,000 Palestinians have been killed, most of them civilians, Israeli air strikes since a 10-day ceasefire collapsed on Tuesday appear to have been focused more intently on Hamas's armed wing. Rocket fire from Gaza continued on Thursday, with several landing in a kibbutz close to the border. Shrapnel from the blast seriously injured one Israeli and narrowly missed a kindergarten, Israel's ambulance service said. (Photo by Amir Cohen/Reuters)
