An Israeli air strike on the emergency department of Nasser Hospital in southern Gaza has killed a well-known Palestinian photojournalist, medical sources and eyewitnesses say.

Hassan Aslih, who was being treated for injuries from a previous Israeli strike, was targeted in what witnesses described as a drone attack on the hospital’s surgical wing.

A doctor there confirmed that Aslih had been at the hospital for nearly a month after surviving an air strike on the same facility in April.

The Israel Defense Forces (IDF) said in a statement it had attacked Nasser Hospital in what it said was “a targeted attack on key terrorists”, but did not name Aslih.
