LONDON — Prime Minister David Cameron announced Wednesday that about 3,800 British troops would be withdrawn from Afghanistan by the end of 2013. Around 5,000 will remain into 2014, Cameron told lawmakers. The announcement comes after a lengthy video call Tuesday between Cameron and President Barack Obama. There are about 60,000 US troops in Afghanistan. Cameron said the decision reflects an increasing confidence in the Afghan National Security Forces. After 2014, some troops will stay on to return equipment and deal with logistics but no details on numbers have been finalized, he said. “We've said very clearly; no one in a combat role, nothing like the number of troops there are now,” Cameron said. “We've promised the Afghans that we will provide this officer training academy that they've specifically asked for. We are prepared to look at other issues above and beyond that, but that is the starting baseline.” The withdrawal of British troops from Afghanistan will start next April, according to Defense Secretary Philip Hammond. Hammond said fewer replacements would be sent over in the spring when the six-monthly rotation of British forces goes ahead as scheduled. — AP
