Varanasi, Oct 15 — A massive explosion triggered the collapse of a two-storey building in Uttar Pradesh's Varanasi on Thursday, leaving two people injured and a woman trapped under the debris, officials said.
The incident took place in the Paigambarpur area under the Sarnath police station area of Varanasi.
According to preliminary information, an illegal firecracker manufacturing unit was operating inside the house. The explosion is suspected to have occurred due to highly inflammable materials on the premises.
Two people were injured in the incident and have been taken to hospital for treatment, while efforts are underway to rescue a woman trapped under the rubble.
Speaking to IANS, DCP Rajesh Pandey said: "Information was received at 5 p.m. that a two-storey building had collapsed. Upon reaching the spot, we found firecrackers scattered around the place, so it is being considered that the incident took place due to the explosion of firecrackers."
He said that according to locals, a woman is trapped under the debris and a rescue operation is currently underway to pull her out.
Uttar Pradesh Chief Minister Yogi Adityanath has directed officials to reach the site immediately and expedite relief operations, NDTV reported.
Further, CM Adityanath has instructed officials to ensure proper medical treatment for those injured. The officials have also been directed to contact the families of the injured and provide them with all possible assistance.
