The explosion was heard more than 10 km away. "It seems to be a suicide attack," said a police officer.

6 people were wounded by the blast at the Police Lines complex. 5 were brought to PIMS hospital and one was brought to Polyclinic. Police officer said the building housed an anti-terror squad and that it stood fairly deep inside the police complex.

According to officials the building was almost empty at the time as most of the policemen were outside on duties due to which the number of injuries and casualties were contained.
