LONDON (AP)  Four passenger trains broke down in the Channel Tunnel between France and Britain, stranding more than 2,000 passengers for hours on Saturday, many without heat, light or water.

Eurostar executives suspended service, blaming wintry weather conditions on the French side of the English Channel for the breakdowns in the trains from Paris. In the afternoon, Eurostar announced on its Web site that there would be “limited service” on Sunday and discouraged unnecessary travel.

The company’s chief executive, Richard Brown, said the problems began because of the abrupt temperature change when trains traveling through extremely cold air in France entered the warm tunnel. The train service links London to Paris and Brussels.

Fatigued passengers arrived in London 10 hours late after a long night trapped on trains, where they said some people suffered panic attacks because of lack of fresh air in dark, unheated cars.
