An Israeli airstrike killed four international aid workers on Monday hours after they transported a shipload of food into Gaza. 

The deceased aid workers volunteered for charity World Central Kitchen (WCK), with footage showing they were found with British, Australian and Polish passports and wearing protective gear. The nationality of the fourth aid worker is not immediately known. 

Australian Prime Minister Anthony Albanese said the death of 44-year-old aid worker Zomi Frankcom from Melbourne was "unacceptable" and requested "full accountability" from Israel's defence ministry.

Palestinian Red Crescent paramedic Mahmoud Thabet said the workers were in a convoy crossing out of northern Gaza when an Israeli missile hit. Thabet said he was told by WCK staff the team had been in the north coordinating distribution of the newly arrived aid and were heading back to Rafah in the south.
