Pakistani security officials have claimed arresting a Tehrik-e-Taliban Pakistan operative who is said to be the mastermind of the suicide attack which targeted former Prime Minister Benazir Bhutto's rally in Karachi in October 2007.
An Interior Ministry spokesman confirmed Azmatullah's arrest who is believed to have plotted the suicide attack in Karachi that killed over 145 and injured nearly 450 people, Xinhua news agency reported.
Bhutto had miraculously survived the attack on the welcome rally, which was organised to celebrate her return to her homeland after a long exile in Dubai. Bhutto was killed two months later in a gun and bomb attack in Rawalpindi.
