A wildfire at a national park in the northern province of Lao Cai was extinguished Tuesday after destroying some 80 hectares of forests in the four days since it broke out.
Ha Cong Tuan, deputy chief of the Department of Forestry, said it took nearly 1,500 people, including local residents, to put out the fire that had spread to 200 ha at the Hoang Lien Sa Pa National Park.
Some troops remain at the site to stop any possible recurrence of the fire, the Vietnam News Agency reported.
On the same day another fire broke out in Sa Pa Town and destroyed 13 to 15 hectares of forest before it was extinguished.
Police are investigating the cause of the two fires.
Elsewhere, in Tram Tau District in Yen Bai, another northern province, local residents and soldiers are fighting a fire that also began Tuesday, the district forest rangers said.
Firefighting attempts are impeded by the area's mountainous location, it said, adding damages have yet to be assessed.
There have been reports that some locals burned their fields to plant corn, but the fire soon got out of control, spreading to other areas, including to a nearby forest.
