Vietnam is evacuating 80,000 people, mostly local tourists, from the central city of Da Nang after three residents tested positive for coronavirus.
The Southeast Asian country is back on high alert after it confirmed its first community infections since April on Sunday.
The evacuation will take at least four days with domestic airlines operating approximately 100 flights daily from Da Nang
to 11 Vietnamese cities, the government said in a statement.
Vietnam has imposed strict quarantine measures and carried out an aggressive and widespread testing programme during the pandemic.
The country is still closed to foreign tourism, but there had been a surge in domestic travellers looking to take advantage of discounted flights and holiday packages to local hotels and resorts.Advertisement
Those returning from Da Nang to other parts of the country will be required to quarantine at home for 14 days, the health ministry said.
