Israeli fighter jets on Tuesday morning bombarded several sites in the southern Gaza Strip, without causing injuries.

Three missiles landed in a militant base of the Al-Ansar Brigades, the military wing of Al-Ahrar movement, in Khan Younis, witnesses said. The airstrike caused material damage, but no injuries were reported.

Another unidentified site was bombed in Rafah.

An Israeli military statement said the forces targeted "two Hamas terror activity sites," confirming direct hits.

It said the airstrikes were in response to gunfire from Gaza on Monday into an Israeli residential kibbutz, Yad Mordechai, near the border.

The overnight fire comes two weeks after an Egyptian-brokered truce halted deadly fighting on the border.

Gaza militant groups fired dozens of rockets into Gaza in June, as Israeli airstrikes pounded the coastal enclave, killing at least 12 Palestinians during a week of cross border violence.
