Army head General Peter Wall said UK forces may have to return to Afghanistan “if the Taliban were to be resurgent and al Qaeda was again establishing sanctuaries.” There are now about 4,100 UK troops in Afghanistan. A former British judge warned that the social media boasts of British jihadist Reyaad Khan, who has claimed participation in Islamic State executions in Syria, could serve as a basis for prosecution in the UK. The UN’s war crimes commission is also “collecting information on perpetrators from all sides including non-state armed groups and ISIS,” according to UN official Paul Pinheiro.
