Israeli attacks across the Gaza Strip have killed at least 33 Palestinians, most of them in an airstrike on a house in Beit Lahiya town in the north of the enclave.

The Beit Lahiya strike killed at least 22 people, including women and children, health officials said. Relatives listed the names of the dead on social media.

More than 30 people were living in the multi-storey building before it was struck, and several family members remained missing as rescue operations continued through the morning, the Palestinian WAFA news agency said.

In nearby Beit Hanoun, where the Israeli forces have operated since October, medics said an Israeli airstrike killed and wounded several people, without giving an exact toll. Rescue workers said several people were trapped under rubble.

Earlier today, at least seven Palestinians were killed and several others wounded in an Israeli airstrike on a house in the Nuseirat camp in central Gaza, medics told Reuters.

The Palestinian Civil Emergency Service and medics said four other people were killed in separate Israeli airstrikes on two houses in Gaza City.
