Algeria hostage crisis: Britons still 'at risk', says PM

Prime Minister David Cameron has said that the number of British nationals at risk in the ongoing hostage crisis at a gas facility in the Algerian desert has "been reduced".

Mr Cameron said that on Thursday night the number of British citizens at risk was fewer than 30 and that number has since been "quite significantly reduced".

The UK has said the incident near In Amenas was "ongoing" and Algerian state media said Islamist militants were holding foreign workers at a treatment plant.

At least four hostages and a number of militants were killed on Thursday when troops stormed the living quarters.
