MASNAA BORDER CROSSING, Lebanon (AP) Powerful new explosions rocked Beiruts southern suburbs late Saturday as Israel expanded its bombardment in Lebanon, also striking a Palestinian refugee camp deep in the north for the first time as it targeted both Hezbollah and Hamas fighters.

Thousands of people in Lebanon, including Palestinian refugees, continued to flee the widening conflict in the region, while rallies were held around the world marking the approaching anniversary of the start of the war in Gaza.

The strong explosions began near midnight after Israels military urged residents to evacuate areas in Dahiyeh, the predominantly Shiite collection of suburbs on Beiruts southern edge. AP video showed the blasts illuminating the densely populated southern suburbs, where Hezbollah has a strong presence. They followed a day of sporadic strikes and the nearly continuous buzz of reconnaissance drones.

Israels military confirmed it was striking targets near Beirut and said about 30 projectiles had crossed from Lebanon into Israeli territory, with some intercepted.

Earlier on Saturday, Israels attack on the northern Beddawi camp killed an official with Hamas military wing along with his wife and two young daughters, the Palestinian militant group said. Hamas later said another military wing member was killed in Israeli strikes in Lebanons eastern Bekaa Valley. The aftermath showed smashed buildings, scattered bricks and stairways to nowhere.

Israel has killed several Hamas officials in Lebanon since the Israel-Hamas war began , in addition to most of the top leadership of the Lebanon-based Hezbollah as fighting has sharply escalated.

At least 1,400 Lebanese, including civilians, medics and Hezbollah fighters, have been killed and 1.2 million driven from their homes in less than two weeks. Israel says it aims to drive the militant group away from shared borders so displaced Israelis can return to their homes.

Iranian-backed Hezbollah, the strongest armed force in Lebanon, began firing rockets into Israel almost immediately after Hamas Oct. 7 attack, calling it a show of support for the Palestinians. Hezbollah and Israels military have traded fire almost daily.
