Hakimullah Mehsud, the boyish-looking Pakistani Taliban commander who was killed Friday in a US drone strike, was one of the world's most wanted men with a $5 million bounty on his head.

Charismatic and fond of the limelight, Mehsud led the Al-Qaeda-linked Tehreek-e-Taliban Pakistan (TTP) to some of the most audacious attacks of its bloody six-year insurgency.

Washington charged Mehsud with terrorism after a suicide attack at a CIA base in Afghanistan in December 2009 killed seven agents, the deadliest attack on the agency since 1983.

The US offered $5 million for information on Mehsud's whereabouts and added the TTP to its blacklist of foreign terrorist groups.
