Those killed in the incident in central Gaza's Deir al-Balah included citizens of Poland, Australia and Britain, as well as one Palestinian, a spokesman for the media office said.

There was no immediate comment from the Israeli military or the WCK.

The WCK delivers food relief and prepared meals for people in need. It said last month it had served more than 42 million meals in Gaza over 175 days.

Chef Jose Andres started the WCK in 2010 by sending cooks and food to Haiti after an earthquake. The organization has since delivered food for communities hit by natural disasters, refugees at the U.S. border, healthcare workers during the COVID pandemic and people in conflicts in Ukraine and Gaza.
