Lebanon says the death toll from Israeli airstrikes on two buildings in central Beirut has risen to 22. Meanwhile, the UN has said its peacekeepers will stay in Lebanon following the injury of two personnel.

Five hospitals have been put on high alert to take in casualties from the blast after what appeared to be two separate strikes.

Palestinian officials say an Israeli strike on a mosque in the Gaza Strip has killed at least 19 people. Israel meanwhile intensified its bombardment of northern Gaza and southern Beirut on Sunday in its widening war on Iran-allied militant groups across the region.
