Corinaldo - Six people died and dozens were injured in a stampede when panic broke out during a rap concert at an Italian nightclub Saturday morning, the fire service said.
Revellers have died after a nightclub stampede near Ancona on the east coast of Italy.

The accident happened around 1:00am (00:00 GMT).
Some reports say there was panic after pepper spray was sacked inside the club in the town of Corinaldo.
A 16-year-old boy told ANSA that disco patrons were dancing while awaiting the start of the concert when the stampede erupted.
A teenager told ANSA he discovered that at least one of the emergency exits was locked when he tried to flee.
Around 1 000 people - many of them young - were in the Lanterna Azzurra (Blue Lantern) club for a performance by Italian rapper Sfera Ebbasta. The boy, who was being treated at a hospital, said that at least one of the emergency exits was locked when he tried to flee.
