"I extend gratitude to all the members of our armed forces who took part in this operation for their professionalism and their valour," the Defence Secretary added.

This mission, to remove militants who endanger our security, demonstrates how our armed forces are ready to step up, continuously, ensuring Britain's security at home and strong abroad."
