Video of an incident Tuesday at an Italian metro station shows a speeding escalator carrying people downward into a pile of bodies, causing more than 20 injuries.
The incident happened at Repubblica metro stop in Rome, and officials say many of those injured were Russians in town for a Champions League soccer game.
The Russian embassy in Italy says up to 30 people were injured, the BBC reports. Citing firefighters, the Associated Press reports that seven people were in serious condition after the incident.
"The scene that we found was people piled up at the bottom of the escalator," the AP quotes Rome provincial fire chief Giampietro Boscaino. "People one on the top of the other looking for help. They had various injuries caused by the escalator that was twisted, therefore serious injuries."
