text: Grandparents have pleaded for the safe return to Australia of two young children whose mother took them from Melbourne to the Islamic State capital in Syria. Former Melbourne woman Dullel Kassab fled to Raqqa in Syria with her children last year, and she regularly boasts on Twitter that her four-year-old daughter and two-year-old son sleep with toy guns next to their beds and her daughter likes watching IS videos of 'Muslims killing bad ppl.' The children's paternal grandparents say they are worried Kassab, 28, is 'brainwashing' the children, after their father was killed near the Syria-Turkey border last year, The Herald Sun reported. Former Melbourne woman Dullel Kassab fled to Raqqa in Syria from Melbourne with her children last year . Kassab posts pictures to Twitter of airstrikes hitting blocks away from their Raqqa apartment . 'We miss the children a lot. Their safety and religion has been compromised and we are deeply worried but unable to do anything about it,' a family spokesman told the Herald Sun. 'We pray they come back but it does not look good.' Kassab's Twitter paints a picture of their life in the city the terrorist group IS have made their headquarters, where the children cannot go to school and airstrikes hit blocks away from their apartment. The 28-year-old has a new husband, as the Islamic State does not permit unmarried foreign women to stay in Raqqa. In social media posts she boasts about her children's distaste for Kuffar (non-believers).
