Conflagrations swept through an area of the Hoang Lien National Park, which is about 3km from Sa Pa district in the northern mountainous province of Lao Cai on March 5.

The blaze continued spreading in the early morning of March 6, the core area of the park because of strong wind and dry weather.

Local civil defence groups, firefighting teams and people are working hard to stop the blaze from spreading.

Over the past month, two major fires already broke out in the park, destroying hundreds of hectares of natural forests .

Hoang Lien national park covers the communes of San Sa Ho, Lao Chai, Ta Van, Ban Ho in Sa Pa district and a part of Muong Khoa commune in Lai Chau province's Than Uyen district. The 30,000-ha park was recognised by the ASEAN Secretariat as the region’s heritage site in 2006.

It also includes a buffer zone of 38,724ha bordering some communes in the three districts of Van Ban, Than Uyen and Phong Tho in Lai Chau province.-VNA
