LONDON - International forces in Afghanistan are ‘preparing to turn a corner’ towards transition and an eventual political settlement, US President Barack Obama said in London Wednesday. He and British Prime Minister David Cameron agreed on the importance of ‘beginning the transition to an Afghan lead for security this year and completing that transition by 2014,’ he said. However, both men stressed that it was essential that any political settlement remained an Afghan-led process, and that the Taliban needed to break with al-Qaeda. (DPA)
