Doctors Without Borders said on Wednesday it was appalled by the death of one of its nurses, who died on Tuesday from shrapnel wounds caused by an Israeli airstrike near his tent five days earlier.
The nurse, Hussein Alnajjar, was a father of three who worked at the international organization's medical clinic in Deir al Balah and Khan Yunis since January of last year.
His sister-in-law and nephew were injured in the same airstrike.
He is the thirteenth Doctors Without Borders medic to be killed since the war in Gaza began.
"We are outraged that military violence continues to kill our Palestinian colleagues," the organization said in a statement.
Death toll of aid workers
At least 540 aid workers have been killed in Israel's nearly two-year-old offensive against Hamas terrorists, launched after the deadly October 7, 2023, cross-border attacks by Hamas terrorists, according to the latest data by the Office for the Coordination of Humanitarian Affairs.
About 1,200 people were killed and 251 taken hostage in the October 7 attacks, according to Israeli tallies.
Aid workers enjoy protection under international humanitarian law, but experts cite few precedents for such cases going to trial, with concerns about ensuring future access for aid groups and difficulty proving intent cited as impediments.
