One Direction fans were 'crushed' during the band's gig in Peru, leaving 47 young people needing medical attention.

The boyband - made up of Harry Styles, Zayn Malik, Louis Tomlinson and Liam Payne - stopped performing during the concert and warned the audience they would walk off stage if they didn't stop pushing each other.

Mario Cassareto from the Estadio Nacional stadium told a Peruvian radio station: ''We treated 47 children with the first stages of asphyxia. Everything is under control. We have nothing to be ashamed of, we've handled the situation well.

''We put in place a second evacuation plan so that the younger fans were not affected.''

He insists venue bosses are working with the police and security companies who were contracted for the show.''

Mario added: ''It's under control. We are still treating those with symptoms of asphyxia that we pulled from the back. The ministry of health has set up tents.''

A video taken from inside the venue shows singer Niall Horan warning the crowd: ''If you don't want anyone to take us off the stage, make sure you stay back.''

Bandmate Liam Payne added: ''Or we'll have to go - and we don't want to go.''

It was only the group's second of 69 shows as part of their 'Where We Are' world tour.

The 'Little Things' hitmakers kicked off their tour at the El Campin Stadium in Bogota, Colombia, where 44,000 fans filled the stadium.
