Palestinian witnesses say Imad Qawasmeh surrendered after Israeli troops surrounded his hideout. They say the building where he was hiding was demolished.
In the Gaza Strip, two Palestinians were killed by Israeli tank fire as forces pushed deeper into the town of Beit Lahiya. Earlier an Israeli airstrike in the town killed a Hamas activist.
