Israeli helicopters fired early Monday two rockets at a house in Gaza City believed to be used to store weapons, witnesses and security sources said.
Witnesses said that the house belonged to a Palestinian resident, and two rockets hit the house, causing severe damage to the building, but no injury was reported.
Israel Radio quoted an army spokesman as saying that Israeli aircraft would target Palestinian houses all over the Gaza Strip suspect of being used to store anti-Israel weapons.
"The Israeli army decided to strike houses in different parts of the Gaza Strip that are used to store homemade rockets and weapons for attacks on Israel," the spokesman said.
