Leaders from the Catholic and Greek Orthodox Church visited Gaza’s only Catholic church on Friday, where a day earlier three people were killed in an Israeli strike. The visit is highly unusual given Israel’s tight control over access in and out of the territory.

The strike killed three people and injured several others, the Latin Patriarchate of Jerusalem, which oversees the small parish, said Thursday.

Top church leaders visited Gaza on Friday after its only Catholic church was struck by an Israeli shell the day before, an attack that killed three people and injured 10. The wounded included a priest who had developed a close friendship with the late Pope Francis.
