Hammond fears for pilot held by IS
Foreign Secretary Philip Hammond has voiced fears for the fate of a Jordanian pilot captured by Islamic State (IS).
The jihadist group claims it shot down the jet being flown by the man - named as Flight Lieutenant Moaz Youssef al-Kasasbeh - near Raqqa.
The pilot and segments of wreckage have been paraded for cameras, with Jordan saying it will hold IS responsible if he is harmed.
It is the first time an aircraft taking part in the US-led bombing campaign in Iraq and Syria has been downed.
An investigation is ongoing as to whether the cause was hostile action or technical failure.
The US has said the plane crashed in northern Syria but that it had not been shot down by Islamic State militants.
Posting on Twitter, Mr Hammond said: "Concerned for Jordanian pilot held by ISIL (IS).
"We stand with Jordan at this difficult time."
The RAF has only been flying sorties in Iraq.
