U-S national security adviser Susan Rice is in Afghanistan to meet with President Hamid Karzai. The visit comes a day after the US-Afghan security pact was thrown into limbo after Karzai refused to sign it. Karzai has told the assembly of tribal elders, known as the Loya Jirga, that the deal should not be signed until after presidential elections in April. The grand assembly had approved the bilateral agreement to keep US forces in the country after 2014. The US says a deal has to be agreed by the end of the year. But Karzai says Washington has to prove its good intentions by keeping its soldiers out of Afghan homes and promoting peace talks with the Taliban. Show Less >>
