MADRID (Reuters) -Around 160,000 people in Spain's northeastern Catalonia region were warned to stay inside on Saturday after a fire at an industrial estate caused a toxic cloud of chlorine over a wide area, emergency services said.
The blaze at a swimming pool cleaning products company started at 2.20 a.m. (0020 GMT) in Vilanova i la Geltru, a town 48 kilometres (30 miles) south of Barcelona and caused a huge plume of chlorine smoke over the area.
