Soccer:Part of a Dutch football stadium under renovation in the city of Enschede collapsed today, trapping an unknown number of people under the rubble.

"Part of the roof has collapsed. There are people under the rubble. We don't know how many," a police spokesman said.

The spokesman could not comment on whether anyone was killed or injured during the incident at FC Twente's ground. The roof's partial collapse probably was related to construction work at the stadium, he added.

A large number of police, fire brigade and ambulances have arrived at the scene, news agency ANP reported.

According to other reports, two support beams buckled, with at least five people injured.

The work was being carried out as part of the club’s development of their stadium to a

32,000-seat arena. The capacity was just 13,500 when the Enschede side moved to the venue in 1998.
