The Foreign Office has confirmed reports that a Briton has been killed by government forces in Syria.

Unconfirmed reports today named the Briton killed as Ali Al-Manasfi, 22, from London.

The man, an American woman and another Westerner were said to have died while taking photographs of military positions in Idlib province, near the Turkish border.

Syrian television has shown what it claims to be the British passport of the man, which appears to show he was born in London in June 1990.
