A cylinder blast in Uttar Pradesh’s Gonda district on Tuesday night killed eight and injured seven and caused two buildings to collapse at Tikri village in Wazirganj area, reported PTI, citing the police.

The incident occurred when one of the families in the village was cooking. The blast led to the collapse of the buildings that were next to each other, trapping 15 people.

Those killed in the incident were identified as two-year-old Mohammad Shoeab, 12-year-old Noori Saba, 11-year-old Meraj, 14-year-old Shahbaz, 35-year-old Nisar Ahmad, 32-year-old Rubina Bano, 28-year-old Shamshad and Sairunisha (35). The injured were being treated at a hospital.

“We received a call about a cylinder blast that made the roof collapse of [the] house,” Superintendent of Police Santosh Kumar Mishra told NDTV. “With the help of the police force and local people we started rescue operations.”

Mishra added that forensic teams were collecting samples from the site and an investigation has been ordered. A team of the anti-terrorism squad was also carrying out investigation, police sources told PTI.

Chief Minister Adityanath expressed grief about the deaths and instructed officials to ensure the injured received efficient treatment. He asked the district magistrate to look into the cause of the incident and submit a report to the government.
