A British national has been killed in Syria, the Foreign Office has confirmed.
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.
The UK-based Syrian Observatory for Human Rights, which opposes President Bashar al-Assad's regime, has reportedly suggested the trio were working with rebels.
A Foreign Office spokesman said: "We understand that a British national has been killed in Syria. Their family have been informed and we are providing consular assistance."
Britain has withdrawn all diplomats from Syria amid the escalating bloodshed.
