Islamabad: The Pakistani Taliban has claimed responsibility for the assassination of former Prime Minister Benazir Bhutto in 2007, saying it killed her as she allegedly planned to collaborate with the US against the mujahideen if she returned to power, according to a book by the banned terror group.

The return of Benazir Bhutto was planned at the behest of the Americans as they had given her a plan against the "Mujahideed-e-Islam".

"Baitullah had received information of the plan," the book claimed, in a reference to slain Pakistani Taliban founder Baitullah Mehsud.

The Daily Times reported that no group had claimed responsibility for Bhutto's murder until the claim in the Taliban's Urdu-language book titled Inqilab Mehsood South Waziristan (From British Raj to American Imperialism).
