An Australian teenager has died after drinking tainted alcohol in Vang Vieng, Laos, Australia’s prime minister said on Thursday, and the US State Department confirmed an American also died in the same party town.

It brings the death toll in the poisoning incident to four.

Australian prime minister Anthony Albanese told parliament that 19-year-old Bianca Jones had died after being evacuated from Laos for treatment in a Thai hospital.

Her friend, also 19, remains hospitalised in Thailand.

Meanwhile, the US State Department confirmed to The Associated Press that an American tourist had also died, but said it had no further comment out of respect to the families.

“This is every parent’s very worst fear and a nightmare that no one should have to endure,” Mr Albanese told lawmakers.

“We also take this moment to say that we’re thinking of Bianca’s friend Holly Bowles who is fighting for her life.”

The two Australian women fell ill on November 13 after a night out drinking with a group.

They are believed to have consumed drinks tainted with methanol, which is sometimes used as the alcohol in mixed drinks at disreputable bars and can cause severe poisoning or death.

New Zealand’s Foreign Ministry said Thursday that one of its citizens was also unwell in Laos and could be a victim of methanol poisoning.

“We have updated our travel advisory for Laos to note that there have been several cases of suspected methanol poisoning after consuming alcoholic drinks,” New Zealand’s Foreign Ministry said.

“Travelers are advised to be cautious about consuming alcoholic beverages, particularly cocktails and drinks made with spirits that may have been adulterated with harmful substances.”

Denmark’s Foreign Ministry, when asked about the poisoning incident, said Wednesday that two of its citizens had died in Laos but would not provide further details.
