The Israeli military has carried out more than 700 strikes on Gaza since it launched a massive offensive on Hamas a week ago, killing at least 435 Palestinians, the army and medics said on Saturday.
At least 75 children and 21 women have been killed during the offensive on one of the world's most densely populated areas, according to Gaza medics.
The raids by warplanes and naval vessels have targeted Hamas government buildings, the homes of Hamas officials, mosques alleged to have stored weapons and tunnels used to smuggle arms and goods into the territory that Israel has kept virtually sealed since Hamas seized power in June 2007.
"There have been approximately 750 strikes," a military spokesman said.
The offensive -- one of Israel's deadliest ever against Gaza -- has killed at least 435 people and wounded another 2,285 others, the medics said.
Israel unleashed "Operation Cast Lead" on December 27 in a bid to halt persistent rocket fire from the territory, but it has failed to stop the attacks.
Militants in Gaza have fired approximately 500 rockets and mortar rounds into Israel over the past week, the army said, killing three civilians and one soldier and wounding several dozen people.
