The Laotian government on Saturday officially acknowledged the mass poisoning that has killed at least six tourists, promising it would bring perpetrators to justice. Two Australian teenagers and a British woman died from suspected methanol poisoning after drinking tainted alcohol in Laos.

The victims were an American, two Danes, two Australians, and a Brit. Australia's prime minister called the ordeal "every parent's very worst fear."

An American is among at least five tourists who have died after visiting a town in Laos where concerns have arisen about alcohol tainted with methanol.
