article: 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).

On her Twitter account she boasts about her children's distaste for Kuffar (non-believers) 'My 4y/o encouraging her little bro to eat his eggs – "C'mon eat ur eggs so u can be big & strong & fight the Kuffar!" Allah yehmikum! [sic]' she wrote in December. '#Awkward Just asked my 4yo wat she wants 2 watch.. "Muslims killing bad ppl" (i.e. #IS vids obv not beheading ones) LOL [sic],' she wrote in October. Kassab has also complained the 12 to 17-year-olds are now regarded as children when 'in the past they were warriors'. And during the Sydney Lindt café siege in December last year she sent a series of tweets joking that it was exciting. 'This is the most excitement Sydney has seen since the 2000 Olympics!' she posted. Kassab also posts pictures of the Islamic State capital - including this of a 'double rainbow' And during the Sydney Lindt café siege last year Kassab sent a series of tweets joking that it was 'exciting' 'I guess attack the coffee shop wasn't a bad idea, It's a long night… One needs caffeine and chocolate!! [sic]' Kassab also posts pictures of the Islamic State capital, and of Nutella and Twix and Snickers chocolate bars with the caption: 'Im really appreciating #globalization right about now! #SimplePleasures Another reason to love #IS [sic].' The 28-year-old's father Jalal Kassab said he was worried about his grandchildren living in a war zone, but said the threat of imprisonment made it difficult for his daughter to return to Australia. 'I know she wants to come back and we are trying everything we can to bring her back,' Mr Kassab told the Herald Sun. Another former Melbourne woman Zehra Duman last month shared a series of propaganda pictures she says shows her 'five star jihad' lifestyle . In photographs posted to a Twitter several women are pictured standing under an Islamic State flag, reclining against a clean white BMW M5 and wielding machine guns . In one tweet, Duman said: 'US + Australia, how does it feel that all 5 of us were born n raised in your lands, & now here thirsty for ur blood?'
