The Foreign Office said it is investigating reports that two British fighters with the Islamic State of Iraq and the Sham were killed during clashes with the Al Nusrah Front in Syria. A House of Commons committee report warned that the number of British fighters heading to Syria has reached alarming levels, and the chairman of committee said “the terrorist threat to the UK is as grave as at any point in the past 13 years.” The EU estimates that over 2,000 Europeans have gone to Syria to fight, mainly from Belgium, Denmark, Germany, the Netherlands, and the UK.
