Pakistani police have arrested two more suspects in connection with the assassination of opposition leader Benazir Bhutto, the interior minister said on Thursday. Bhutto was killed in a gun and bomb attack on Dec. 27 as she was coming out of an election rally in the city of Rawalpindi, adjoining the capital Islamabad. "Right now, I can only say that two suspects have been apprehended in this connection," Interior Minister Hamid Nawaz told Reuters. Last month, authorities arrested 15-year-old Aitezaz Shah who admitted being a back-up suicide bomber for a team that assassinated Bhutto. Shah and his "handler" Sher Zaman were captured from the northwestern city of Dera Ismail Khan.
