An explosion near the Punjab provincial assembly in the Pakistani City of Lahore killed at least 13 people and wounded 83 others on Monday.
A police inspector general in Punjab province said five police officers were among the fatalities when an explosion rocked a protest organised by Pakistan’s chemists and pharmaceutical manufacturers.
Authorities say it was a suicide attack and that the bomber exploded himself when successful negotiations were underway between police officials and the protesters.
A faction of the Pakistani Taliban claimed responsibility of the attack.
