An Israeli air strike targeted a house in the Nuseirat refugee camp, killing at least 20 people, including six children and five women.
At least 51 people have been killed in Israeli attacks across Gaza since dawn, according to medical sources in the besieged enclave.
Gaza’s civil defence agency says 29 people have been killed in Israeli attacks around Kamal Adwan Hospital in northern Gaza.

Four doctors were killed at Kamal Adwan Hospital in besieged northern Gaza on Friday, after Israeli forces stormed the compound, killing and injuring dozens of people in surrounding areas, eyewitnesses told CNN.

Israeli troops also forced health care workers and patients to leave the facility, and destroyed critical medical supplies, according to a statement by Dr Hussam Abu Saifya, the hospital director.

In the early hours of Friday, the Israeli military sent two plain clothed messengers into the hospital, who told people over a megaphone to evacuate, Abu Saifya added. The military detained a “large number” of young men in the two-hour raid, including health workers and Palestinians who had sought refuge, added Abu Saifya.

A São Paulo state police officer is seen leading an unarmed man to the edge of an overpass in an impoverished neighbourhood of Latin America’s largest city.

Seconds later, the officer pushes the man, who falls backwards from a height of three metres into a shallow stream of murky, sewage-laden water. Three other officers can be seen watching the scene unfold, taking no action.

The victim – later identified as a motorcycle delivery driver – was rescued by local people and taken to a hospital. He survived. By Thursday morning, the officer responsible had been arrested, while 12 others involved in the operation were suspended.
