Lebanese officials have asked people who lost relatives in recent Israeli airstrikes to provide DNA samples to match with unidentified remains.

Lebanon’s Internal Security Forces on Monday called on residents across the country to visit police stations with an identity card to give their samples. It said more than one person from each family should provide a sample, if possible.

European Union foreign ministers called Monday for an immediate ceasefire between Israel and Hezbollah and have expressed support for U.N. peacekeepers in southern Lebanon.

“Arms should now be silenced, and the voice of diplomacy should speak and be heard by all,” EU foreign policy chief Josep Borrell told reporters after chairing an emergency meeting.

An Israeli strike on a Beirut apartment block killed four people on Monday, a Lebanese security source said, the first such raid on the heart of the city since the outbreak of the war in Gaza last year.

Israel has turned its focus from Gaza to Lebanon in recent days, carrying out strikes on Hezbollah targets that killed the Iran-backed group's leader Sayyed Hassan Nasrallah on Friday.

The Israeli strike that killed Hezbollah's leader Sayyed Hassan Nasrallah was a "measure of justice" for victims of a four-decade "reign of terror," U.S. President Joe Biden said.

The comments came after Hezbollah confirmed that Nasrallah, one of the group's founders, was killed in an Israeli airstrike in Beirut's southern suburbs the previous day.

The Israeli military says it has killed another high-ranking Hezbollah official in an airstrike.

The military said Sunday that it killed Sheikh Nabil Qaouq, the former deputy head of Hezbollah's Executive Council, in an airstrike the day before. The Israeli army said Qaouq is a member of Hezbollah's central council and the head of the group's preventive security unit.

Lebanon’s state news agency says an Israeli airstrike early Sunday on a village in northeast Lebanon destroyed a home, killing 11 people.

Six of the bodies were recovered from under the rubble as the search continued for the remaining five in the village of al-Ain, reported National News Agency.

In its first statement since the recent escalation with Israel and following the killing of Hezbollah leader Sayyed Hassan Nasrallah, Lebanon's army called for calm among the Lebanese "at this dangerous and delicate stage."

Government officials fear that the country’s deep political divisions at a time of war could rekindle sectarian strife and violence in the small country.

Hundreds of thousands of people in Lebanon have been displaced from the ongoing conflict between Hezbollah and Israel, a Lebanese cabinet minister spearheading the country’s emergency response said.

Environment Minister Nasser Yassin said the government estimates that about 250,000 people have left their homes and taken refuge in government-run shelters and informal ones. However, he told the Associated Press the total number is about “four times as many directly affected and/or displaced outside the shelters.”

Air raid sirens sounded across central Israel, including at the Tel Aviv international airport, shortly after Prime Minister Benjamin Netanyahu landed after a trip to the U.S.

The Israeli military said a missile launched from Yemen was intercepted shortly after the sirens were heard. There were no reports of injuries.

A prominent general in Iran's paramilitary Revolutionary Guard died in an Israeli airstrike that killed Hezbollah leader Sayyed Hassan Nasrallah in Beirut's southern suburbs, Iranian media reported Saturday.

The killing of Gen. Abbas Nilforushan marks the latest casualty suffered by Iran as the nearly yearlong Israel-Hamas war in the Gaza Strip teeters on the edge of becoming a regional conflict. His death further ratchets up pressure on Iran to respond, even as Tehran has signaled in recent months that it wants to negotiate with the West over sanctions crushing its economy.
