More than seven Palestinians, including children, were injured in an Israeli airstrike on the Gaza Strip, local health officials said on Sunday.
The Israeli military planes delivered strikes against the town of Beit Hanoun in northeast Gaza. Israeli sources reported that Palestinian militants had fired three rockets on southwestern Israel that caused no casualties or destruction.
Israel has warned it will respond to any instance of Israeli territory shelling by militants in the Gaza Strip.
In the past two weeks, the Israeli airstrikes have killed three and wounded over 20 Palestinians, including children.
The Gaza Strip has been subject to Israeli attacks and economic blockade since the radical Islamic group Hamas took control of the enclave in the summer of 2007, ousting President Mahmoud Abbas's Fatah movement.
Israeli Operation Cast Lead, which lasted for three weeks and ended in mid-January 2009, killed some 1,300 Palestinians in Gaza and injured over 5,300 others. Up to 50,000 people were also left homeless in the enclave of 1.5 million.
