A major fire at a chemical factory near Barcelona has released a huge toxic chlorine cloud over the region, prompting authorities to order more than 160,000 residents and tourists to stay indoors.
The blaze broke out at around 2.30am at a chemical storage plant in Vilanova i la Geltru, a coastal town about 25 miles from the Catalan capital. Firefighters were seen battling through the night to control the flames as thick plumes of smoke rose over the area.
