Four children aged from nine to 12 years were killed on Saturday when a sports center collapsed near Barcelona in strong winds which battered parts of northern Spain and southwest France. At least 11 adults were killed in separate incidents in Spain and France as gales buffeted the region for a second day, cutting power, disrupting flights and blocking roads. In the sports center disaster, winds of more than 100 kmph (62 mph), ripped the roof off a building next to a baseball court in Sant Boi, causing the breeze block walls to collapse inwards. Around 20 people, mostly children, were inside the building, authorities said. Four children, members of a junior baseball team, were killed. Eight people were injured, including six children.
