The British jihadi bride whose four-year-old son recently appeared in an IS execution video was once a devout Christian who loved going to church, her father has said. 25-year-old Grace, who now goes by the name Khadijah, was religious. She would read her Bible and pray all the time. Her father said, ‘We called her Grace after Amazing Grace, the hymn. She went to church every week without fail, often three times.’ Khadijah converted to Islam in 2010 and is believed to have been radicalised online. She fled to Syria in 2012 with her son, Isa, who appeared in a ten-minute IS propaganda video released last week entitled 'A message to David Cameron'. It showed five hostages being killed.
