Six people were killed and as many as 60 were injured in a stampede at a nightclub on Italy's Adriatic coast Saturday, authorities said.
An Italian fire brigades official told NBC News that it is believed the stampede was the result of a panic sparked by someone using pepper spray at the venue in the town of Corinaldo.
A police official said an Italian rapper, Sfera Ebbasta, was performing at the Lanterna Azzurra nightclub Saturday night.
The dead included three girls, two boys and a woman who had accompanied her daughter to the venue, police said. At least 12 people were in serious condition, police said.
A teenager told the ANSA news agency at least one of the emergency exits was locked when he tried to flee. Authorities were investigating.
