GAZA - Israeli F16 warplanes continued pounding Gaza for a fourth day in a row, killing four Palestinians on Saturday morning, after a night of airstrikes that were focused mainly on government facilities.

The four Palestinians killed this morning were members of the armed wing of Islamic Hamas movement which controls the Gaza Strip. Israeli drones hit them in two separate attacks in central and southern Gaza Strip, medical sources and witnesses said.

The attacks put the number of deaths of Palestinians since Wednesday to 35, including at least 10 civilians. Around 300 people were injured since Israel unleashed "Operation Pillar of Defense".

At dawn, the F-16 fighter jets dropped five bombs at the headquarters of Hamas cabinet, destroying a four-story building. The raid caused severe damage in neighboring houses in Gaza City.

Another airstrike was reported on the main police compound.

In the northern town of Jabaliya, 30 Palestinian civilians were injured when the aircrafts hit a house of an Interior Ministry official. The house was empty at the time, but the injuries came from nearby houses as air concussions that followed the strike shatter the windows.
