Israel launched air strikes on the Gaza Strip on Thursday, damaging school and houses.
An Israeli military spokeswoman said the strikes were aimed at three separate targets. No casualties were reported.
The air strikes were launched overnight after a mortar fired by Gaza fighters wounded an Israeli man at a farm.
On Thursday, Israeli missiles hit a training field of the Hamas armed wing, causing damage to several nearby houses and a primary school of 700 students, witnesses said.
"All the windows in the three floors of our houses were smashed. Our bedroom door was blown in," said one woman. "Every time they hit the training camp we get hurt," her son said.
Israel ended 38 years of Gaza occupation in 2005 but it began siege in 2007.
Palestinians and some United Nations officials say Israel's occupation can only truly end when it gives up control of Gaza's borders, coast and airspace.
