More than one hundred young people, presumably of neo-Nazi affiliation, attacked the audience at a music festival in central Russia on Sunday. Over ten people were taken to hospital and one girl was reported killed.

According to witnesses, the men were armed with clubs and sticks when they stormed the rock concert, which was being held at a youth summer camp in Miass. They began assaulting members of the crowd as well as police and security.

Local media reported that gunshots could be heard in the area and news channel Vesti 24 reported that one 14-year old girl had been killed in the attack. But later a local police department spokesman denied reports that a 14-year-old girl died of stab wounds.

Echo Moskvy radio station claimed 15 suspects have been apprehended, while the rest of the group were able to flee the scene.

Authorities have not yet commented on the event or suggested possible motives.

According to RIA NOVOSTI source, the organizers of a rock festival say there were enough security and police but they were unprepared for such an attack.

A group of about 150 men armed with clubs and rubber bullet guns attacked security guards and police, who were unarmed, as well as spectators.

"There was enough security and there were enough police. Their task was to ensure order and they were not prepared for an armed attack," festival organizer Valikhan Turgumbayev said.

"Initially there were 70 security guards and police, as well as 20 [security] volunteers at the festival."

The situation was brought under control within 15 minutes when police reinforcements arrived he said, adding that the attack had been a well planned action, prepared by "professionals."

Turgumbayev said he was unaware of what could have caused the attack.

Some 6,000 people visited the Tornado-2010 festival, featuring some of Russias most popular rock bands.

Local media have suggested political struggles are the most likely cause of the attack and that Turgumbayev, the event's main organizer who was going to run for the local legislature in October, used the festival for political campaigning.
