Ton of marijuana catches fire in Texas warehouse

US authorities were trying to find out Thursday who stored 907 kilograms of marijuana in a warehouse that caught fire. It took more than 35 firefighters about half an hour to extinguish Wednesday's blaze with 3,785 liters of water and 19 liters of chemical suppressant, Edinburg Fire Chief Shawn Snider said. Snider said the firefighters were exposed to so much marijuana smoke they would not be able to pass a drug test, despite the air packs they wore to prevent them from inhaling toxic or hazardous fumes. US Immigration and Customs Enforcement agents were called in to investigate the origin of the drugs, and the Hidalgo County fire marshal was investigating whether arson may have been the cause.
