A man who appears to behead US journalist James Foley in a video released by The Islamic State (IS) has a British accent, the UK foreign secretary has said.
In the video the militant says the killing was revenge for US air strikes against its fighters in Iraq.
Phillip Hammond told BBC Breakfast that there are a "significant number of British nationals in Syria and Iraq", and pose a direct threat to the UK.
