LONDON (Reuters) - Pakistans security service provides weapons and training to Taliban insurgents fighting US and British troops in Afghanistan, despite official denials, Taliban commanders say. A number of middle-ranking Taliban commanders revealed the extent of Pakistani support in interviews for a BBC Two documentary series, 'Secret Pakistan, the first part of which was broadcast on Wednesday. A former head of Afghan intelligence also told the programme that Afghanistan gave Pakistans former president Gen Pervez Musharraf, information in 2006 that Osama bin Laden was hiding in northern Pakistan close to where the former al Qaeda leader was eventually killed by US special forces in May. Admiral Mike Mullen, then the top U.S. military officer, accused Pakistani intelligence last month of backing violence against U.S. targets including the U.S. Embassy in Kabul. He said the Haqqani network, an Afghan militant group blamed for the September 13 embassy attack, was a 'veritable arm of Inter-Services Intelligence agency (ISI). Pakistan denies the US allegations. One Taliban commander, Mullah Qaseem, told the BBC the important things for a fighter were supplies and a hiding place. Pakistan plays a significant role. First they support us by providing a place to hide which is really important. Secondly they provide us with weapons, he said, according to excerpts provided by the BBC. The BBC said Pakistan strongly denied the allegations made in the programme. Gen Athar Abbas, director general of the Inter Services public relations and official spokesman for the Pakistan military, told the BBC: To say that these militant groups were being supported by the state with the organised camps in these areas ... I think nothing could be further from the truth.
