MIRAMSHAH, Jan 26: The outlawed Tehrik Taliban Pakistan (TTP) has claimed responsibility for bomb explosions in Karachi and Lahore on Tuesday and said the blasts were aimed at killing security personnel because they serve the US interests.

“The security forces will face attacks as they protected US interests in Pakistan. The state of lawlessness is so bad that President Asif Ali Zardari has obtained the services of US-based notorious security agency Blackwater,” TTP spokesman Azam Tariq said while talking to by phone from an undisclosed location on Wednesday.
