Two children in a Kurdish-controlled camp in north-east Syria may be eligible for Australian citizenship if they can prove their fathers were Australian Islamic State fighters, according to a former Deputy Secretary of the Australian Immigration Department. The children's mothers are ISIS brides without Australian citizenship, but DNA testing could establish paternal links to Australian fighters. Sydney doctor Jamal Rifi is separately negotiating with Syrian officials to bring 11 ISIS brides and 23 children to Australia, criticising both major political parties for their handling of the situation.
