The video of an incident that occurred Tuesday in an Italian subway station shows an escalator that carries people into a pile of bodies, causing more than 20 injuries.

The video – published by NBC News, Sky TG24 and other outlets – shows the faulty escalator that drops passengers in a pile. Some jump from the escalator to avoid body mass, from which audible cries can be heard.

The incident occurred at Rome's Repubblica metro station, and officials said many of the injured were Russians in town for a Champions League football match.

The mayor of Rome, Virginia Raggi, said that witnesses reported that people were jumping and dancing on the escalator before the accident, according to the ANSA news agency. The news agency also said that maintenance of the escalators was done every month.

The Russian Embassy in Italy announced that about thirty people were reportedly injured, reported the BBC. Quoting firefighters, the Associated Press reports that seven people were in serious condition after the incident.

"The scene we found was that of people crammed at the bottom of the escalator," said AP quoting Rome Fire Chief Giampietro Boscaino as saying. "People who find themselves on the other side are looking for help. They suffered various injuries caused by the twisted escalator, resulting in serious injury. "
