Police charge key Bhutto suspect

Ms Bhutto was killed while campaigning for general elections

Police in Pakistan have formally charged a Taleban leader, Baitullah Mehsud, with planning the assassination of Benazir Bhutto, officials have said.

Four other men were also charged in the attack on the opposition leader and former prime minister, said the chief investigator, Chaudhry Abdul Majeed.

A judge issued arrest warrants for the five suspects after charges were filed.

Five men have already been arrested over the 27 December suicide bomb attack which killed Ms Bhutto.

Baitullah Mehsud is based in the troubled region of South Waziristan, on the border with Afghanistan. He has denied any involvement.

Last month, police said cousins Rufukat and Husnan Gul had confessed to giving Ms Bhutto's attacker a bomb vest and a pistol.
