Prime Minister David Cameron has said it will be "mission accomplished" when British forces leave Afghanistan next year, by helping to prevent the country from becoming a haven for terrorists again.

He was speaking during a visit to Helmand province. The Prime Minister said combat troops could leave next year with "heads held high" after a "job well done".
