GAZA CITY (CNN) -- Israeli airstrikes pounded targets in Gaza on Saturday, killing at least 155 people, Palestinian medical sources said. An Israeli army spokeswoman said her country is ready to continue the attacks "as long as it takes."
Palestinian medical sources said at least 250 people had been wounded in the air raids, and the militant group Hamas vowed to retaliate.
The strikes followed several days of rocket attacks from Gaza into Israel.
Hamas police stations were hit, killing many senior police commanders, a reporter in Gaza said.
Maj. Gen. Tawfeeq Al-Jaber, a senior commander in the Hamas police force, was killed, as was Ismail Jabari, who headed the special police force in Gaza, Palestinian sources said.
Israeli Maj. Avital Leibovich told CNN the military began the attacks "in order to preserve the security situation in Israel..."
