Local media reported that an apparently armed portable grenade launcher exhibited at an interactive show in Chernihiv went off in a crowd. The investigative bureau said it was looking into the incident.
"SBI is investigating a case in which children were injured at a weapon show in Chernihiv. Five people were injured in the incident, including four children aged from 2 to 12 years," the agency said.
Chernihiv is the capital of Chernihiv Oblast, under Ukrainian control. Viacheslav Chaus, who was appointed regional governor by President Volodymyr Zelensky last year, said the toddler’s condition was grave.
