Israeli police stormed into the Al-Aqsa Mosque in Jerusalem’s Old City early Wednesday, firing stun grenades at Palestinian youths who hurled firecrackers at them in a burst of violence during a sensitive holiday season. Palestinian militants in Gaza responded with rocket fire on southern Israel, prompting repeated Israeli airstrikes.

The fighting, coming as Muslims mark the holiday month of Ramadan and Jews prepare to begin the Passover festival on Wednesday evening, raised fears of a wider conflagration. Similar clashes two years ago erupted into a bloody 11-day war between Israel and the ruling Hamas militant group in Gaza. The official Palestinian news agency Wafa said that dozens of worshippers who were spending the night praying were injured in the police raid. The Israeli military said one soldier was shot in a separate incident in the occupied West Bank.
