Five people, including three children, were injured when a cylinder used to fill balloons exploded in Ujjain in Madhya Pradesh.
Police said a balloon vendor was filling air at a busy New Year’s Eve fair when the incident happened.
Many children had gathered around him to buy balloons, police said. The condition of one of the injured children, who is eight years old, became critical. He was taken to a hospital in Indore for advanced treatment. The rest are being treated at a local hospital.
The explosion was so violent that walls at the fair were damaged.
Local official Preeti Gaikwad said the accident happened due to an incorrect mixture of hydrogen gas in the cylinder. The parts of the damaged cylinder were sent to a laboratory for examination.
“I was setting up shop when the blast happened,” said balloon salesman, Altab Shah. He was also injured.
The fair was hosted by a local politician amid the COVID-19 threat.
