CIA-operated Predator drones may strike Laden’s hide-out without taking permission beforehand from Islamabad if the US locates him in Pakistan’s rugged tribal areas, a source close to the arrangement told ‘The Washington Times’.

The right to launch attacks to US was granted by Musharraf when the Pakistan had joined the war against terrorism, the source said.

The US has options for sending special operations teams into Pakistan if Laden’s exact location is determined, but military officials said it would be the Predator, not boots on the ground, that would be dispatched to kill the al Qaeda leader.

This is because a Predator could be airborne - or redirected in flight - in a matter of minutes. In contrast, special operations forces in Afghanistan would have to be assembled, briefed on the mission and then dispatched by helicopter - a time-consuming and risky process.

By not requesting Pakistan’s approval first, the US would avoid the risk of breaching operational security.

Washington still harbours suspicions about Pakistan’s Inter-Service Intelligence agency (ISI), which helped establish pro-al Qaeda Taliban rule in Afghanistan,the daily said.
