At least three people were killed and 28 others injured in a suspected time-controlled explosion in the Anarkali bazaar area of Lahore on Thursday afternoon.
Lahore police spokesperson Rana Arif said a bomb was "planted" in a motorbike in the bustling market.
The CCTV footage of the blast shows the intensity of the explosion that left several shops damaged.
Video captured by locals show burning vehicles in the crowded market, where the wounded are crying for help.
An ethnic-nationalist militant group, the Baloch National Army has claimed responsibility for the attack. The group primarily operates in Balochistan Province, but it has increased its activities in Punjab Province in recent months, a worrying sign for Prime Minister Imran Khan's government.
Meanwhile, Prime Minister Khan condemned the bombing in a statement, urging authorities to provide the best possible medical facilities to the wounded. He has also sought a report from the Punjab government over the incident.
