Afghanistan: Pakistan accused of backing Taliban
Pakistan has been accused of playing a double game, acting as America's ally in public while secretly training and arming its enemy in Afghanistan according to US intelligence.
In a prison cell on the outskirts of Kabul, the Afghan Intelligence Service is holding a young man who alleges he was recruited earlier this year by Pakistan's powerful military intelligence agency, the ISI.
He says he was trained to be a suicide bomber in the Taliban's intensifying military campaign against the Western coalition forces - and preparations for his mission were overseen by an ISI officer in a camp in Pakistan.
After 15 days training, he was sent into Afghanistan.
"In Afghanistan we saw an insurgency that was not only getting passive support from the Pakistani army and the Pakistani intelligence service, the ISI, but getting active support” End Quote Bruce Riedel Adviser to President Obama in 2009
"There were three of us. We were put into a black vehicle with black windows. The police did not stop the car because it was obviously ISI. No-one dares stop their cars. They told me... you will receive your explosive waistcoat, and then go and explode it."Taliban bases in Pakistan
The man recruited to be a suicide bomber changed his mind at the last minute and was later captured by the Afghan intelligence service.
But his story is consistent with a mass of intelligence which has convinced the Americans that, as they suspected, for the last decade Pakistan has been secretly arming and supporting the Taliban in its attempt to regain control of Afghanistan. (What rubbish! Read Colin Powell's Dec. 2010 request for massive funding of the PakMil).
These suspicions started as early as 2002, when the Taliban began launching attacks across the border from their bases in Pakistan, but they became more widely held after 2006 when the Taliban's assault increased in its ferocity, not least against the ill-prepared British forces in Helmand province.
The final turning point in American eyes was the attack on Mumbai when 10 gunmen rampaged through the Indian city, killing 170 people - two weeks after Barack Obama's US presidential election victory in November 2008.
Despite Pakistan claiming it played no part in the attack, the CIA later received intelligence that it said showed the ISI were directly involved in training the Mumbai gunmen.
President Obama ordered a review of all intelligence on the region by a veteran CIA officer, Bruce Riedel.
"Our own intelligence was unequivocal," says Riedel. "In Afghanistan we saw an insurgency that was not only getting passive support from the Pakistani army and the Pakistani intelligence service, the ISI, but getting active support."
Training and supplies
Pakistan has repeatedly denied the claims. But the BBC documentary series Secret Pakistan has spoken to a number of middle-ranking - and still active - Taliban commanders who provide detailed evidence of how the Pakistan ISI has rebuilt, trained and supported the Taliban throughout its war on the US in Afghanistan.
"For a fighter there are two important things - supplies and a place to hide," said one Taliban commander, who fights under the name Mullah Qaseem. "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."
Another commander, Najib, says: "Because Obama put more troops into Afghanistan and increased operations here, so Pakistan's support for us increased as well."
He says his militia received a supply truck with "500 landmines with remote controls, 20 rocket-propelled grenade launchers with 2000 to 3000 grenades... AK-47s, machine-guns and rockets".
