JERUSALEM—At least seven people were killed and three were injured Friday night when a Palestinian gunman opened fire outside a Jerusalem synagogue, in what authorities said was an act of terrorism.

The attack was Jerusalem’s deadliest since 2008, Israeli police said, and came at a time of heightened tensions following a military raid to capture militants in the West Bank city of Jenin that left nine Palestinians dead on Thursday.
