Israel launched new air strikes on Gaza today, targeting fields in the north of the area from which Palestinian militants have been firing rockets into Israel.
A military spokeswoman said two raids had been carried out near the northern Gaza town of Beit Hanun. The area was empty at the time but had been used recently by militants.
Thousands of Palestinian homes in the Gaza Strip are still without electricity after Israeli missile strikes hit a power station.
The multiple raids were accompanied by artillery fire, used against Gaza for the first time since the 1967 Middle East war.
An Israeli army official said the strikes were ordered in response to cross-border rocket fire from Gaza. He said the Israeli army had not deliberately set out to cut electricity supply.
The surge in violence between the two sides has resulted in the cancellation of a summit between the Israeli Prime Minister, Ariel Sharon, and the Palestinian President, Mahmoud Abbas. The meeting was due to have been held on Sunday.
