An Australian teenager has become the sixth foreign tourist to die in a suspected mass methanol poisoning in Laos, as a growing list of countries warned of the potentially fatal consequences of drinking tainted alcohol in the Southeast Asian country.

The Laos government said on Saturday (Nov 23) that it was "profoundly saddened" by the deaths of foreign tourists in Vang Vieng, with the toll from a suspected methanol poisoning incident now at six.

This week, an American man and two Danish women, aged 19 and 20, died in the same town due to methanol poisoning.
