Foreign secretary Philip Hammond has confirmed that a British hostage is being held by the Islamic State of Iraq and Syria (ISIS).
The foreign secretary said the government will explore "every possible option" to protect the British hostage, who was first publicly identified in a video released on Tuesday showing the execution of American journalist Steven Sotloff.
Hammond said the British hostage, who is not being named in the UK at the request of his family, was the subject of a failed rescue attempt earlier this year.
