Israeli airstrikes on Lebanon over the last day have killed at least 40 people including several children, Lebanese authorities said on Saturday, after heavy Israeli bombardment pounded the southern suburbs of the capital Beirut overnight.

At least seven people were killed in the coastal city of Tyre late on Friday, Lebanon’s health ministry said. The Israeli military has previously ordered swathes of the city to evacuate but there were no orders published by the Israeli military spokesperson on social media platform X before Friday’s strikes.

The ministry said two children were among the dead. Rescue operations were ongoing and other body parts retrieved in the aftermath of the attack would undergo DNA testing to identify them, the ministry added.

Strikes in nearby towns on Saturday killed 13 people, including seven medics from rescue groups affiliated to Hezbollah and its ally Amal, the health ministry said.

At least 20 more people were killed in Israeli strikes on Saturday across the eastern plains around the historic city of Baalbek, the health ministry said.

The Israeli military said it had struck Hezbollah infrastructure sites in the areas of Tyre and Baalbek, including fighters, “operational apartments,” and weapons stores.

The Lebanese health ministry said Israeli attacks have killed at least 3,136 people and wounded 13,979 in Lebanon over the last year. The toll includes 619 women and 194 children.

Israel has been locked in fighting with Lebanese armed group Hezbollah since October 2023, but fighting has escalated dramatically since late September of this year. Israel has intensified and expanded its bombing campaign, and Hezbollah has ramped up daily rocket and drone attacks against Israel.

The Iran-backed group announced more than 20 operations on Saturday, as well as one that it said fighters carried out the previous day against a military factory south of Tel Aviv.

More than a dozen Israeli strikes also hit the southern suburbs of Beirut overnight, once a bustling collection of neighbourhoods and a key stronghold of Hezbollah.

Now, many buildings have been almost entirely flattened, with Hezbollah’s yellow flags jutting out from the ruins, according to Reuters reporters who were taken on a tour of the area by Hezbollah.

Some buildings were partially damaged by the strikes, leading some floors to collapse and sending furniture and other personal belongings spilling onto parked cars below.

Men and women were picking through the rubble for their belongings, shoving blankets and mats under their arms or into black plastic bags.

“We are trying to gather as many (of our possessions) as we can, so we can manage to live off them, nothing more,” said Hassan Hannawi, one of the men looking for his belongings.
