May 8 (UPI) — Australia has charged three women linked to ISIS with crimes against humanity after they returned home from Syria.

They had allegedly moved to Syria to be part of the Islamic State caliphate in Syria, but once it fell, they were in refugee camps guarded by Kurdish guards. They were part of a group of 13 people who were returned to Australia. It’s not yet clear if other people returning to Australia will face charges.

Australia’s Prime Minister Anthony Albanese said in February that he would not allow the refugees to repatriate to Australia.

Kawsar Ahmad, 53, and her daughter Zeinab Ahmad, 31, appeared in a Melbourne court Friday. Kawsar Ahmad was charged with four counts of crimes against humanity. Police allege she went to Syria in 2014 and kept a female slave in her home. Zeinab Ahmad faces two similar charges.

Another adult child of Kawsar Ahmad, Zahra Ahmad, arrived in Melbourne Thursday, but was not arrested.

Janai Safar, 32, appeared in a Sydney court and was charged with entering and remaining in a declared conflict zone and joining ISIS. She returned to Sydney Thursday with her son.

Safar’s lawyer, Michael Ainsworth argued for her release on bail, saying her alleged offenses happened when she was 21, and she has been in a refugee camp for nine years.

“This young lady … lived in truly horrific conditions in these refugee camps for many years,” Ainsworth said. “She has significant community ties here in Australia, she’s one of seven children. There’s a place for her to live.”

The Australian Federal Police said Kawsar Ahmad moved to Syria with her husband and children in 2014 and was complicit in buying a female slave for $10,000, “and knowingly kept the woman in the home.”

Zeinab Ahmad allegedly also traveled to Syria and kept a female slave in the home. A slavery conviction can bring up to 25 years in prison.

Federal police assistant commissioner for counter-terrorism Stephen Nutt said Thursday night that planning for the return of people from the Middle East began in 2015.

“Australian joint counter-terrorism teams methodically investigated all Australians who travelled to declared conflict areas and will ensure those who are alleged to have committed a criminal offense are put before the courts,” Nutt said.
