"It took the Americans 11 years to kill Osama but for us it is easy, we will take our Dire Revenge™ in less than a few months."Khalid and his men are now hiding in the mountains, and appear to be well-armed with assault rifles and other weapons. They are also shown with a laptop and a radio.

Meanwhile on Wednesday, dozens of fighters attacked security checkpoint in northwestern Pakistain, killing two coppers and wounding several others.

The Taliban have staged a number of attacks in Pakistain since bin Laden was killed in a US raid on May 2 near the Pak capital Islamabad.
Last Friday, at least 76 people were killed in a double suicide kaboom on a Frontier Constabulary training centre in the northwestern town of Charsadda.
The Pak Taliban said they carried out the attack - this year's deadliest on the security forces - to avenge bin Laden's death in a compound in the Pak town of Abbottabad.
