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. <br/><br/>A book by the banned terror group says, 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'.<br/><br/>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'.<br/><br/>Pakistan Peoples Party (PPP) chief Bhutto, 54, was killed in a suicide attack in Rawalpindi shortly after she had addressed an election rally on December 27, 2007.<br/><br/>Former President Pervez Musharraf had blamed the Tehreek-e-Taliban Pakistan for the attack but the outfit had denied it.
