Taliban leader Mullah Baradar is believed to have informed US whereabouts of Al-Qaeda Chief Osama Bin Laden, a UK paper claimed. According to the report, in return the US promised to pullout troops from Taliban strongholds in Afghanistan once Osama had been killed or captured. Until now it has been believed that Osama Bin Laden was caught when the US intercepted a phone call made by his courier Abu Ahmed al-Kuwaiti. But new reports suggest it was actually Baradar who told the US where he was hiding. Baradar was arrested in a joint Pak-US operation last year in Karachi and was interrogated in prison before being released last October.
