Caretaker PM ‘trying to fill the gaps’ amid mass displacement of people from their homes

• Middle East crisis – live updates

Lebanon’s caretaker prime minister, Najib Mikati, announced on Monday that he would meet donor countries to seek additional funding for Lebanon’s growing displacement crisis, as hundreds of thousands of people fled Israel’s widening aerial campaign.

“We are trying as much as possible to fill the gaps; as I said yesterday, it is not an easy process,” Mikati said, announcing that he would ask donors on Tuesday to give money to Lebanon through the UN.

The success of Israel’s operation stands in sharp contrast to its misjudgment of Hamas’s intentions before 7 October

A hundred munitions – including, it is believed, US-made 2,000lb bombs – were used by the Israeli air force in Friday evening’s overwhelming air raid that killed the Hezbollah leader, Hassan Nasrallah, in an underground complex hidden in the southern Beirut suburb of Dahieh.

Nasrallah, who was careful to the point of paranoia about his security arrangements and only rarely appeared in public, would have given little notice of his plan to undertake the fateful trip to the meeting.

For months, the staff at Rafik Hariri university hospital had been preparing for the worst. Nurses ran drills in parking garages, practising transferring patients from the wards to the bombproof concrete structures. A building was left empty on the hospital campus so that if mass bombing occurred, medics could bring their families with them and not worry about their safety.

On Friday night, the drills seemed to pay off. Dozens of bombs were dropped on Dahiya, the southern suburbs of Beirut, sending residents running to the safest place they could think of – the nearby hospital.

Residents of Lebanon’s capital flee their homes and seek shelter as the death toll from Israel’s airstrikes rises

Gunshots fired into the air, women wailing in the streets, the ever-present buzz of drones and the distant thud of Israeli airstrikes: this was the sound of mourning in Beirut on Saturday. Hassan Nasrallah, who led Hezbollah for 32 years, was dead, killed in an Israeli airstrike on Dahieh, in the southern suburbs of Beirut, the day before.

For many in Lebanon, his killing had been unimaginable. But Israel’s war with Hezbollah had long surpassed what was previously thought possible. Pagers had exploded in hands, walkie-talkies blew up in belts and Israeli warplanes killed hundreds in half a day. The death of Nasrallah was one more blow to the Lebanese psyche, already struggling to grasp soaring death tolls and, for some, the loss of their home overnight.
