KABUL (Reuters) - Afghan President Hamid Karzai ratcheted up his criticism of the United States on Sunday, marring a debut visit by the new U.S. defence secretary, Chuck Hagel, and highlighting tensions that could undermine Washington's strategy to wind down the unpopular war.
A day after two Taliban bombings killed 17 people, Karzai accused the United States and the Taliban of colluding to convince Afghans that foreign forces were needed beyond 2014, when NATO is set to wrap up its combat mission and most troops withdraw.
