RAF transport planes have taken part in a humanitarian air drop to the Iraqi town of Amirli, Defence Secretary Michael Fallon said.
The RAF dropped 14 tonnes of food and water for a Shia population there.
The Hercules aircraft helped an international effort to resupply the town which has been under siege by Islamic State (IS) militants for nearly two months.
"We have been putting in humanitarian aid, I can confirm that last night I authorised two Hercules to participate in the big aid drop on Amirli, a town that's been under siege for nearly two months," Mr Fallon told Sky News.
A British family have told ITV News of their devastation after discovering a close relative is fighting with the Islamic State in Iraq.
A French journalist who was held hostage with James Foley in Syria has told ITV News it was "devastating" to see his murder.
