Breaking News Islamic terrorist who came to Britain on small boat and can't be deported over concerns that HIS life would be in danger is spotted shopping in the King's local Co-op A dangerous Islamic terrorist who was part of a ruthless Isis gang behind a string of horrific public executions was free to walk the streets near Windsor Castle after being allowed to stay in Britain on human rights grounds, SWR News can reveal. Iraqi Mohammed Yaseen, a hardened terrorist since he was just 16, was a member of the Al Qaeda group that beheaded Briton Ken Bigley, later joining Isis and a unit that carried out barbaric stonings, beheadings and mass executions. Yaseen – who a British court chillingly heard 'posed a danger to the whole of the UK' – was released from prison last week after serving just six months of a two-year sentence for illegally entering the country across the Channel on a small boat. He was put up in a bail hostel in Windsor, where the MoS last week observed him shopping in a Co-op close to Windsor Castle. He made the break for Britain after serving a near five-year prison term in Germany for membership of Isis. In a damning indictment of the UK's asylum system, Yaseen has reapplied to stay in this country, thereby halting Home Office attempts to deport him. The MoS understands that the Foreign Office has raised concerns he could face 'mistreatment' if he were returned to Iraq because of his terrorist past. Politicians reacted furiously last night over the terror threat Yaseen posed close to the royal palace, where King Charles will host a state banquet for the Sultan of Oman on Thursday. The Prince and Princess of Wales, along with their children, George, 13, Charlotte, 11, and eight-year-old Louis, live nearby, at Forest Lodge on the Windsor Great Park, as do the Duke and Duchess of Edinburgh, who reside at Bagshot Park. MPs are angry the taxpayer is footing the bill for the convicted terrorist's bid to stay in the UK. Legal experts say Yaseen will receive legal aid for his application and that if he were to fight it all the way to the European Court of Human Rights, the taxpayer could have to fork out £500,000. Other experts have told the MoS that since Yaseen will have to be kept in taxpayer-funded accommodation, be given food allowance and be monitored, the annual cost of keeping him in the UK could reach £85,000. Chris Philp MP, Shadow Home Secretary, told the MoS: 'We are paying through the nose to feed, clothe and house individuals who pose a clear threat. If Andy Burnham took this seriously, he would deport this man at once.' A court in Germany heard in 2020 that Yaseen was involved in bomb attacks that killed US troops. The Dusseldorf court also heard that he operated as a security guard for Isis during stonings, beheadings and at least two mass executions where the victims included children.
