MADRID: More than 250 people have been injured, five of them seriously, after part of a wooden promenade collapsed at a music festival in Spain, local officials said on Monday.

The seafront platform, which was 30 meters (98 feet) long by 10 meters wide, was packed with people watching a rap artist in the northwestern city of Vigo when it suddenly collapsed just before midnight on Sunday, Vigo mayor Abel Caballero told reporters at the scene.
