At least six tourists who traveled to Laos have died in recent days, prompting international alarm about the dangers of consuming alcoholic drinks that contain methanol.

Six people are so far dead, with the cause suspected as methanol-tainted drinks in the town of Vang Vieng, Laos.

The U.S., Australia and U.K. have issued warnings for travelers in Vang Vieng after several tourists died in a suspected methanol poisoning outbreak.
