New video released by the Israeli Army shows an airstrike carried out in Gaza.

The Israeli government says they targeted two weapons manufacturing sites and that the operation was a response to rocket attacks that injured four people in Israel.

Islamic Jihad and the Popular Resistance Committee claimed responsibility for the attacks against Israel.

Cross border fire began early in the weekend after Israel blew up a car in Gaza killing two militant leaders. The sound of explosions and rocket fire reverberated across the coastal Palestinian enclave and parts of southern Israel on Saturday.

At least fifteen militants have been killed in Gaza since the attacks started Friday.
