Taleban's '$100m opium takings'
Taleban insurgents took an estimated $100m (£50m) from Afghanistan's opium trade in 2007, the head of the UN's anti-narcotics agency told the BBC.
Antonio Maria Costa, head of the United Nations Office on Drugs and Crime (UNODC) said it was raised by a 10% tax on farmers in Taleban areas.
"We estimate the farm gate value is $1bn [£500m] in 2007," said Mr Costa.
Mr Costa estimated the takings were beyond $100m (£50m) as opium produced two other forms of Taleban revenue.
