Map shows Pakistan Taleban spread

A map produced by the BBC suggests only 38% of Pakistan's North West Frontier Province (NWFP) and surrounding areas is under full government control, as the Taleban extend their influence.

The map, compiled by the BBC's Urdu language service, was based on local research and correspondent reports as well as conversations with officials.

But Pakistani President Asif Ali Zardari has rejected the findings, telling the BBC it was an "incorrect survey".
