The Islamic State militant shown beheading US journalist James Foley in a recent IS propaganda video is said to be a Londoner called “John” who guards IS’ Western hostages in Raqqah, Syria; UK authorities are working with the FBI in tracking him down and have asked Londoners to help identify him. Khadijah Dare, 22, a Lewisham woman married to a Swedish IS fighter who calls himself Abu Bakr, has reportedly vowed to become the first woman to behead a British or US prisoner; she is thought to be in Syria with her husband and three-year-old son. Brustchom Ziamani, 19, a Congolese convert to Islam, was arrested in Camberwell on Aug. 19 while carrying a bag with a hammer and a knife wrapped in an Islamic flag; he has been charged with preparing terrorist acts. The suspect had told another person he intended to commit a Lee Rigby-type attack on military or government personnel.
