The last UK base in Afghanistan has been handed over to the control of Afghan security forces, ending British combat operations in the country.
The union flag was lowered at Camp Bastion, while Camp Leatherneck - the adjoining US base - was also handed over to Afghan control.
British Commander Brigadier Robert Thompson said of the troops that have died or been wounded, "we will hold them in our hearts till the very end of our days... but we have made a difference".
