An Italian rapper says he is “profoundly sorry” after six people died during a stampede at one of his gigs in the north-east of Italy.

The stampede at an overcrowded nightclub on Italy’s central Adriatic coast has killed five teenagers and a woman who had accompanied her daughter to the event, police said.

Sfera Ebbasta says his love and support goes out to the families of those killed overnight.

Dozens of people were also injured.

Video taken outside the venue in the town of Corinaldo, near Ancona, showed scores of teenagers rushing out of a door and surging towards a low railing or wall near the exit.

The barrier appeared to give way and a cascade of teenagers tumbled over it, falling on top of each other.

The “giving way of two parapets due to the crush of the young people getting out” probably caused the tragedy, interior minister Matteo Salvini told RAI.

The bodies of the victims were found near a low wall close to an exit, firefighters’ spokesman Dino Poggiali earlier told Sky TG24 News. News reports said the wall was about 3ft to 5ft high. Overcrowding is also suspected.

Ancona chief prosecutor Monica Garulli told reporters at the scene: “The number of tickets sold is about 1,400, compared to a capacity of about 870.”

Mr Salvini said it was “probably true that there were … more people inside than was permissible”.

State radio said about 1,000 people were in the disco when the stampede erupted.

Mr Carrozza said the dead teenagers – three girls and two boys – were aged 14 to 16 and the woman was 39. Of the 59 who were injured, 13 were in serious condition, he said.

The radio report said most of the fatalities suffered crushed skulls.
