KABUL (AFP) - A suspected suicide bomber carrying a bag of explosives was shot dead on Monday near the site of a major meeting of Afghan elders set to discuss relations with the US, officials said. The man was gunned down and two accomplices arrested in Kabul, hours after the Taliban claimed to have published a top-secret security plan for the loya jirga, which starts Wednesday and will bring together more than 2,000 elders. Afghan officials and the NATO-led foreign military in Afghanistan said the document was fake, but the leak and the killing highlight tight security around the jirga.
