Six people, all but one of them minors, were killed and about 35 others injured in a stampede of panicked concertgoers early Saturday at a club in a small town on Italy's central Adriatic coast, authorities said.

The dead included three girls and two boys and an adult woman, a mother who had accompanied her daughter to the disco in Corinaldo, where an Italian rapper was entertaining the crowd, police chief Oreste Capocasa said in nearby Ancona.

GOOGLE MAPS Revellers have died after a nightclub stampede near Ancona on the east coast of Italy. Italian fire officials said concertgoers at a nightclub in the town of Corinaldo, on the Adriatic Sea, panicked and ran for the exits after someone sprayed a noxious substance.

Italian fire officials and ANSA news agency said the audience at Italian rapper Sfera Ebbasta's concert at the Lanterna Azzurra nightclub panicked and ran for the exits after someone sprayed a substance similar to pepper spray.
