CIA backs tribal leader link to Bhutto's death

American intelligence believes former Pakistan Prime Minister Benazir Bhutto was murdered in an operation masterminded by a tribal leader linked to al-Qaida.

Baitullah Mehsud who also has strong ties to the Taliban, heads a network in South Waziristan, a lawless border region next to Afghanistan. He has been blamed for an organised campaign of assassinations of Pakistani officials and suicide bombings in the country.
