A jihadist who fled Manchester for Syria has been identified as a key member of a clique of British fighters that include the notorious Islamic State extremist Mohammed Emwazi, it has been reported.

Raymond Matimba is believed to have left Britain in 2014 to link up with terrorists in the region. According to the Daily Telegraph’s video, he went on to join a group of high-profile British jihadists that included Emwazi, the executioner also known as Jihadi John. The newspaper also reports that Matimba had links to the Manchester suicide bomber Salman Abedi.

Zimbabwean-born Matimba, who adopted the nom de guerre Abu Qaqa al-Britani al-Afro, is said to have become a leading sniper for Isis. The 28-year-old spent time in Raqqa, Isis’s de facto capital, and reportedly may still be alive.
