The Israel Defence Forces said a preliminary investigation found the convoy of World Central Kitchen charity workers, who were delivering food in Gaza, was struck due to “misidentification”.

Israel’s explanation of how the seven aid workers were killed has been labelled “insufficient and unacceptable” by Albanese.

“What isn’t good enough are the statements that have been made, including that this is just a product of war,” he said on Thursday.

“This is against humanitarian law.”

Albanese said he demanded transparency and accountability in a phone call with Israeli Prime Minister Benjamin Netanyahu on Wednesday morning about Frankcom’s death.

“I want those findings to be made public so that we find out how exactly this can occur,” he said.

Netanyahu said early this week that the Israeli military had carried out the “unintended strike”.

“Unfortunately in the past day there was a tragic event in which our forces unintentionally harmed non-combatants in the Gaza Strip,” he said in a video statement.

“This happens in war. We will do everything to prevent a recurrence.”

World Central Kitchen founder Jose Andres said the seven aid workers had been targeted by the Israeli military “systematically, car by car”.

The chef said the charity had told the military of their workers’ movements.

“This was not a bad luck situation where ‘oops’ we dropped the bomb in the wrong place’,”Andres said.

Frankcom’s family said they support a war crimes investigation and charges if they are justified.

They described Israel’s response to the deaths as “disappointing” and said the lives of humanitarian workers should always be protected.

Asked if the investigation should go to the International Criminal Court, Albanese said the government will take advice on an “appropriate way forward”.

Israeli government spokesman Avi Hyman said the strike on the aid workers was a “grave mistake” and not something the military would have done on purpose.

He also claimed there was no “imminent famine” in Gaza.

“It’s wildly exaggerated and the reason that it’s being exaggerated in the international community is because people want to immediately stop the war,” he said.

Oxfam Australia said people in northern Gaza have been forced to survive on an average of 245 calories a day – less than a can of beans – since January.

Oxfam also found that total food deliveries allowed into Gaza for the more than 2 million people living there amounted to an average of 41 per cent of the daily calorie intake needed per person.

Writing on X, formerly Twitter, Israel’s top diplomat in Australia Amir Maimon said the military “does and will continue to do everything in its power to prevent harm to civilians”.

“Israel will thoroughly investigate this tragedy to guarantee the safety and security of aid workers in Gaza,” the Israeli ambassador said.

Maimon had not met with officials from the Department of Foreign Affairs and Trade in Canberra as requested, citing health issues.
