Following the rioting at Jerusalem’s Al-Aqsa Mosque, Israel launched airstrikes in southern Lebanon and the Gaza Strip and was met with rocket fire in response. 

Israel launched airstrikes in southern Lebanon and Gaza Strip after rockets were fired at Israel from both areas, marking a further escalation in the region after violence at Jerusalem’s Al-Aqsa Mosque. The Israeli military targeted installations of the Palestinian militant group Hamas in southern Lebanon, while Gaza militants resumed rocket fire toward southern Israel. The fighting comes during a delicate time when Jews are celebrating the Passover holiday and Muslims are marking the Ramadan holy month. The rare attack from Lebanon raised fears of a wider conflagration as Israel’s bitter enemy, the Iran-backed militant group Hezbollah, holds sway over much of southern Lebanon. The violence at the Al-Aqsa Mosque has resonated across the region, with condemnations pouring in from Muslim leaders.
