London, June 19 (IANS) Three sisters from Britain's Bradford city, who along with their nine mi**r children were reported missing after a pilgrimage to Saudi Arabia, have entered Syria, a media report said on Friday, citing an Islamic State (IS) smuggler. Khadija, Sugra and Zohra Dawood -- all in their 30s -- and their nine children were split into two groups before they crossed into Syria on Wednesday and Thursday, BBC reported. The sisters are believed to have travelled to the crisis-hit country to join their younger brother Ahmed, who left Britain in 2013 to join the radical group.
