Israeli air strikes hit four sites in the Gaza Strip on Saturday, causing damage but no injuries, officials said.

Two of the sites were in Gaza City while the other two were in Beit Lahia, in the north of the enclave. All of the sites have been previously targeted by the Zionist forces, the official said.

Occupation military said in a statement it had "targeted four locations that were components of Hamas's operational infrastructure in the northern and central Gaza Strip" in response to the rocket.

The occupation military said a rocket launched from the strip hit a building in the occupied territory of Sderot late Friday, damaging it but causing no injuries.
