Israel has decimated Hamas’s military wing, along with much of Gaza. But the group’s small-scale, hit-and-run approach poses a threat in the enclave’s north.

Gaza's Hamas-run health ministry has said at least 87 people were killed and more than 40 injured in Saturday's Israeli air strike on the city of Beit Lahiya in the north of the Palestinian enclave. The ministry said a number of people were still under the rubble after a residential area was hit.

Thousands of Palestinian civilians have been filmed fleeing northern Gaza amid fierce fighting and a resurgence of Hamas activity. Footage shows hundreds of Gazans moving through the rubble of a destroyed street as an Israeli armoured car watches on from the side.
