Israel said Thursday that it “deeply regrets” a deadly strike on Gaza’s only Catholic church that killed three people. The office of Israel’s Prime Minister Benjamin Netanyahu said that “Israel deeply regrets that a stray ammunition hit Gaza’s Holy Family Church.

Several people have been injured at the Holy Family Church in Gaza City, with some unconfirmed reports that it was hit by Israeli artillery shells.

The church was damaged in the attack, officials said, in what witnesses said appeared to be an Israeli tank shelling.
