A large group of chemists and pharmaceutical manufacturers were gathered in front of the provincial assembly to protest a government crackdown against the sale of illegal drugs. There was a significant presence of law enforcers in the area while the protest was ongoing.
Up to 400 people had attended the protest, according to an AFP reporter who was on the scene when the explosion occurred.
Rescue services, including ambulances and fire tenders, reached the scene soon after the attack. An emergency was also declared in all hospitals of Lahore. Majority of the casualties were shifted to Mayo Hospital and Ganga Ram Hospital.
