Eleven Palestinians seeking aid were among at least 33 killed by Israeli gunfire and strikes across Gaza on Wednesday, rescuers and medics say.
A spokesman for the Hamas-run civil defence agency said Israeli forces "opened fire and launched several shells" at thousands of people who were queuing for desperately needed food supplies on the main Salah al-Din Road.
The Israeli military said troops operating in the Nuseirat area fired warning shots overnight after a group approached them in a manner that posed a potential threat, but that it was unaware of any injuries.
Another 19 people were killed in three Israeli air strikes in northern and southern Gaza, according to the civil defence agency.
They included eight who died when a home was hit in the Zeitoun area of Gaza City, it said.
