A powerful bomb blast at Kaka Sahib shrine in Nowshehra claimed four lives and left at least 35 people injured on Sunday. Sources said nine among the injured were in a critical condition. An emergency was imposed in all hospitals of Peshawar and Nowshehra. As per details, a bomb fixed on a bicycle exploded near the central gate of Kaka Khail Baba shrine. The explosion occurred when there were a large number of visitors present in the shrine. Interior minister Rehman Malik condemned the incident and said a remote controlled device operated the bomb through an illegally acquired mobile phone SIM. All business centres in the area remained closed on Monday to mourn the Kaka Sahib incident. The Tehreek-e-Taliban Pakistan steered clear of responsibility, saying the bombing was aimed at defaming the militant outfit.
