Lebanon's government says up to 1.3 million people have been internally displaced, whilst Prime Minister Najib Mikati warned of the "largest displacement” in the country's history.

The Israel Defense Forces (IDF) has been issuing evacuation orders to residents across the country, including areas of Beirut.

In the south, the army instructed residents of several villages to leave their homes and "immediately head north of the Awali River," which meets the coast about 50 km (30 miles) from the Israeli border.The Israeli military says air strikes in Lebanon are targeting Hezbollah infrastructure.

It regularly adds it wants to ensure the safe return of tens of thousands of residents of Israeli border areas displaced by attacks from the Iran-backed group.

About 60,000 people have been evacuated from northern Israel because of near-daily attacks by Hezbollah. But some rockets have reached further south and damaged homes in and around the coastal city of Haifa.

On the Lebanese side, many Israeli air strikes targeted the city of Tyre, the Bekaa Valley, and Beirut, according to the BBC’s analysis of the latest monthly data collected by Acled.Most of the strikes on Beirut have targeted Dahieh, a southern suburb that is home to thousands of civilians. The Israeli military claims the area is home to Hezbollah’s command headquarters.

A series of Israeli strikes on buildings in the area killed Hezbollah's leader Hassan Nasrallah on 27 September.

Separate data from the US-based Armed Conflict Location and Event Data Project (Acled), which has been analysed by the BBC, indicates at least 2,700 attacks by the Israeli military on Lebanese areas from 1 September until 11 October 2024. While these attacks primarily focus on southern border areas, they have also extended to northern and central regions.

Hezbollah has carried out around 540 attacks against Israel in the same timeframe, according to Acled. Each Hezbollah attack can include a barrage of rockets, missiles and drones.

He said there are insufficient shelters to accommodate so many evacuees.

“I saw children sleeping in the streets,” Karlsson added, urging humanitarian organisations to coordinate their efforts to address the escalating crisis.

Lebanese officials say at least 2,350 have been killed and over 10,000 injured in Israeli attacks. The Lebanon health minister said many casualties were civilians.

On the Israeli side, 60 people have been killed and more than 570 wounded by Hezbollah attacks, Israeli authorities say.

“Collateral damage is inevitable in war”, Amos Yadlin, the former head of Israeli military intelligence, told the BBC.

The retired major-general blamed Hezbollah for the war and claimed Israel’s ground offensive would force the group out from the border areas.

Zwijnenburg, from the Pax for Peace organisation, however, has warned of the impact of Israel’s military campaign on civilians and the populated areas.

“The heavy blast radius kills and maims civilians nearby”, he said, in reference to Israeli air strikes.

“Open-source data combined with satellite imagery also showed that civilian infrastructure such as irrigation channels, gas stations and electricity grids were damaged, which is worsening the humanitarian situation,” he added.
