At least 12 people were killed in a series of bomb and suicide explosions on the US consulate in the high-security zone of Peshawar on Monday, Apr 5.
"If you remember, similar attacks were carried out when president Asif Zardari delivered his first presidential speech," said senator Haji Adeel, senior vice president of the Awami National Party (ANP).
Adeel also said that the al Qaeda was working closely with the Pakistani Taliban.
"Once again the militants did the same action. It clearly aims to create a crisis in Pakistan and aims derail the political process in the country," he added.
The banned Tehreek-e-Taliban Pakistan (TTP) claimed responsibility for the blasts.
Speaking to media, Azam Tariq, a purported TTP spokesperson, claimed responsibility for the attack on the US Consulate but denied responsibility for Lower Dir suicide blast.
