Israel said Thursday that it “deeply regrets” a deadly strike on Gaza’s only Catholic church, which killed three people.

Three people were killed and 10 injured in the Israeli strike Thursday on the Holy Family Church, the only Catholic church in Gaza, said the parish and the Vatican.

Israeli forces killed at least 22 people in attacks in the Gaza Strip on Thursday, including two people who died in a strike on a church that late Pope Francis used to speak to regularly, medics and church officials said.
