Seven aid workers from the World Central Kitchen (WCK) have been killed in an Israeli air strike in Gaza, the charity's founder says.
The victims were British, Polish, Australian, Palestinian and also included a dual US-Canadian citizen, WCK said.
Israel's Prime Minister Benjamin Netanyahu has acknowledged that the Israeli military hit "innocent people", describing it as tragic and unintentional.
"It happens in war, we check it to the end, we are in contact with the governments, and we will do everything so that this thing does not happen again," he said in a video message.
