A fire in the Paris Metro on Saturday caused light injuries to about 15 people, most of whom suffered from smoke inhalation, a fire official said. "Two carriages were hit by a fire which gave off a large plume of smoke," captain Laurent Vibert, spokesman for the Paris fire department told LCI television. "We have about 15 light injuries, mainly people who inhaled the smoke." "The fire is under control," he said, adding that more than 200 firefighters had been called to the scene, according to Reuters. The RATP, which runs the Metro, said the fire was probably caused by a short-circuit and that there was no panic among passengers. It said only three people suffered minor injuries. The incident comes amid heightened security in European capitals after attacks on London's transport system last month.
