Australian leader says the death of Australian aid worker is ‘completely unacceptable’.

Frankcom was one of four international aid workers that Palestinian officials say were killed along with their Palestinian driver on Monday in an Israeli air attack in central Gaza’s Deir el-Balah.

Speaking at a news conference in Brisbane, Albanese said Frankcom’s death was “completely unacceptable” and “beyond any reasonable circumstances”.

“This news today is tragic. DFAT have also requested a call-in from the Israeli ambassador as well,” Albanese said, referring to Australia’s Department of Foreign Affairs and Trade.

“We want full accountability for this. This is a tragedy that should never have occurred.”

Albanese also reiterated his calls for a “sustainable ceasefire”.

“Australians want to see an end to this conflict,” he said.

Frankcom had worked at the United States-based aid organisation World Central Kitchen since 2019, most recently serving as senior manager for Asia operations in Bangkok, according to her LinkedIn profile.

Those killed in Monday’s attack also include a UK and a Polish national, according to Gaza officials.

WCK founder Jose Andres confirmed on social media that “several” of the organisation’s staff had been killed in an Israel air attack, saying he was “heartbroken and grieving for their families and friends and our whole WCK family”.

Al Jazeera’s Hind Khoudary, reporting from the al-Aqsa Martyrs Hospital in Deir el-Balah, where the deceased’s remains were taken, said she had spoken with the aid workers earlier in the day.

“Everyone in the hospital is amazed and astonished, they don’t believe Israeli forces targeted internationals,” Khoudary said.

The Israeli military has said it is investigating “to understand all the circumstances of the incident”.
