Live blog: David Cameron in Afghanistan
Updated on 10 June 2010
Cameron's visit comes after a suicide bomb ripped through a wedding party last night, killing 40 and injuring 77 people, in the heart of the Taliban's stronghold in southern Afghanistan.
Earlier yesterday, four American troops died when their helicopter was shot down in Helmand province in an operation to evacuate two British soldiers wounded in a gun battle with insurgents in Sangin.
A British serviceman was killed in a separate bomb blast bringing the total UK soldiers killed in Afghanistan to 294.
