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.
A series of strong explosions were reported near midnight on Saturday after Israel's military called on residents to evacuate areas in Beirut's Haret Hreik and Choueifat neighbourhoods.

Earlier on Saturday, Israel's 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 Lebanon's eastern Bekaa Valley. Residents confronted the aftermath: smashed buildings, scattered bricks and stairways to nowhere.
Israel's military said it killed two senior officials with Hamas' military wing in Lebanon, where fighting has sharply escalated.
At least 1400 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 began firing rockets into Israel almost immediately after the Hamas' October 7 attack, calling it a show of support for the Palestinians. Hezbollah and Israel's military have traded fire almost daily.
Last week, Israel launched what it called a limited ground operation into southern Lebanon after a series of attacks killed longtime Hezbollah leader Hassan Nasrallah and others.
The fighting is the worst since Israel and Hezbollah fought a brief war in 2006. Nine Israeli soldiers have been killed in the ground clashes that Israel says have killed 440 Hezbollah fighters.

Iran's foreign minister, Abbas Araghchi, told reporters in Damascus that "we are trying to reach a cease-fire in Gaza and in Lebanon." The minister did not name the countries putting forward initiatives, saying they include regional states and some outside the Middle East.
Araghchi spoke a day after the supreme leader of Iran praised its recent missile strikes on Israel and said it was ready to do it again if necessary.
On Saturday evening, Israeli Prime Minister Benjamin Netanyahu said "Israel has the duty and the right to defend itself and respond to these attacks, and it will do so".
On Lebanon, he said "we are not done yet."
Israel's military on Saturday said about 90 projectiles were fired from Lebanon into Israeli territory. Most were intercepted, but several fell in the northern Arab town of Deir al-Asad, where police said three people were lightly injured.
At least six people in Lebanon were killed in more than a dozen Israeli airstrikes overnight and into Saturday, according to the Lebanese state-run National News Agency.
Nearly 375,000 people have fled from Lebanon into Syria in less than two weeks, according to a Lebanese government committee.
Associated Press journalists saw hundreds continuing to cross the Masnaa Border Crossing on foot, crunching over the rubble after Israeli airstrikes left huge craters in the road leading to it on Thursday. Much of Hezbollah's weaponry is believed to come from Iran through Syria.
The Israeli military said special forces were carrying out ground raids against Hezbollah infrastructure in southern Lebanon, destroying missiles, launchpads and weapons storage facilities. It said troops dismantled tunnel shafts that Hezbollah used to approach the Israeli border.
More evacuation orders in Gaza
Almost 42,000 Palestinians have been killed in Gaza during the war, according to the Health Ministry there, which does not differentiate between civilian and militant deaths.
Palestinian medical officials said Israeli strikes in northern and central Gaza on Saturday killed at least nine people. One in the northern town of Beit Hanoun killed at least five, including two children, according to Gaza's Health Ministry. Another hit a house in the Nuseirat refugee camp, killing at least four, Awda hospital said.
