Major world powers opened talks Thursday seeking an end to the grinding conflict in Afghanistan, drafting plans to hand over security responsibilities to local forces and quell the insurgency with an offer of jobs and housing to lure Taliban fighters to renounce violence. Afghan President Hamid Karzai greeted delegates from about 70 nations and institutions in London, seeking to win new international support after more than eight years of combat which is threatening to exhaust public good will in the West. U.S. Secretary of State Hillary Clinton, U.N. Secretary-General Ban Ki-moon and NATO chief Anders Fogh Rasmussen also joined talks aimed at setting targets to transfer security control of several Afghan provinces to the local police and military by the end of 2010.
