An Australian government review into the deaths of 7 aid workers in Gaza in April found that serious failures to follow procedures by the Israeli military led to the air strikes on their vehicles, Reuters reports quoting Australian Foreign Minister Penny Wong.

An Australian review into the deaths released on Friday found serious failures to follow Israel Defence Forces (IDF) procedures, mistaken identification and errors in decision-making.

The IDF has called the incident a grave mistake which should not have occurred. Wong said Australia would push for full accountability for those responsible, including criminal charges if appropriate.

“The Military Advocate General of Israel is still to decide on further action,” she said in a statement. “Our expectation remains that there be transparency about the Military Advocate Generals process and decision.”
