Islamabad: On the outskirts of the Pakistani capital lives a militant considered so powerful that Osama bin Laden consulted with him before issuing a fatwa to attack American interests.

Fazle-ur-Rahman Khalil heads Harakat-ul-Mujahedeen, a terrorist group closely aligned with al-Qaeda and a signatory to bin Laden's anti-US fatwa in 1998.

Khalil has also dispatched fighters to India, Afghanistan, Somalia, Chechnya and Bosnia, was a confidante of bin Laden and hung out with 9/11 mastermind Khalid Sheikh Mohammed.

Pakistani authorities are clearly aware of Khalil's whereabouts. But they leave him alone, just as they tolerate other Kashmiri militant groups nurtured by the military and its intelligence agency to use against India.

Khalil is also useful to the authorities because of his unusually wide contacts among Pakistan's many militant groups, said a senior government official who is familiar with the security agencies and who spoke on condition he not be identified fearing repercussions.

Khalil's presence in an Islamabad suburb, confirmed to The Associated Press by Western officials in the region, underscores accusations that Pakistan is still playing a double game fighting some militant groups while tolerating or supporting others even after the solo US raid that killed bin Laden on May 2.

The US Congress, enraged that bin Laden found refuge for at least five years down the street from Pakistan's equivalent of West Point, has threatened to cut off the billions of dollars in aid being spent here.
