At least 12 people have been killed, including children, and dozens are missing after a war-damaged building collapsed in the Gaza Strip, according to local rescue teams.

Video footage shows the search for bodies and survivors continuing in the rubble of the multi-storey building in the Tal al-Hawa area of Gaza City, its floors sandwiched together.

Locals said 10 families had been living in the apartments despite warnings that they were unsafe.

Members of the Hamas-run Civil Defence rescue service said they had initially been working with “empty hands” due to tight Israeli restrictions on equipment allowed into Gaza. However, they have since been able to borrow some heavy machinery.

On Tuesday, Israeli air strikes in Gaza killed at least five Palestinians, including two children and a Hamas commander, according to health officials and Hamas sources.

The Israeli military said it killed a Hamas commander in southern Gaza and another fighter in the north. In both cases, a child was also reportedly killed.

Separately, the British charity Medical Aid for Palestinians said that a patient was killed by an Israeli drone at a health centre it supports in Jabalia in northern Gaza.
