DEIR AL-BALAH, Gaza Strip (AP) A new round of airstrikes hit Beirut suburbs late Sunday as Israel intensified its bombardment of northern Gaza and southern Lebanon in a widening war with Iran-allied militant groups across the region. Palestinian officials said a strike on a mosque killed at least 19 people.

A year after Hamas Oct. 7 attack , Israel has opened a new front in Lebanon against Hezbollah, which has traded fire with Israel since the war in Gaza began.

Israels military confirmed a Hezbollah attack on the northern city of Haifa, though it was not immediately clear whether shrapnel from fallen projectiles was from rockets or interceptors. Hezbollah said it tried to hit a nearby naval base. The Magen David Adom ambulance service said it treated 10 people, most of them hurt by shrapnel.

Israel also has vowed to strike Iran after a ballistic missile attack on Israel last week. The widening conflict risks further drawing in the United States, which has provided crucial military and diplomatic support to Israel. Iran-allied militant groups in Syria, Iraq and Yemen have joined in with long-distance strikes on Israel.

Israel is on high alert ahead of memorial events for the Oct. 7 attack, while rallies continue around the world marking the anniversary.
