The Typhoon FGR4s were backed up by a Voyager tanker plane.

"They were among numerous British troops on duty over the festive period. This operation, to remove terrorist threats who endanger our security, demonstrates how UK forces are ready to step up, throughout the year, ensuring Britain's security within its borders and powerful internationally."
