An American man charged with plotting the attacks on Mumbai was a double agent for both the United States and al-Qaeda terror group Lashkar e Taiba, Indian officials have claimed.
David Headley, a Pakistan-born American national arrested in Chicago in October, is alleged to have carried out reconnaissance missions in the run-up to the Mumbai attacks, in which 166 people were killed.
He is also believed to have been present in the terrorists' "control room" in Pakistan where their handlers directed the killing spree over an open telephone line.
