At least seven people have been found dead in the northern part of the country after a landslide triggered by heavy rain buried the van they were travelling in, state media reports said.
Northern Vietnam has entered its rainy season, with heavy downpours and flooding making travel along mountain roads treacherous.
The landslide hit the 16-seater van around 4am local time as it drove through Bac Me district in Ha Giang province, state media said.
Rescuers had recovered seven bodies, including a boy.
Six others were found alive and taken to a nearby hospital, state media said, adding that rescuers were searching for those missing.
Photos and videos on state media showed excavators, ambulances and hundreds of rescue workers at the muddy hillside road.
Reports said three people travelling in a separate vehicle had been at the site when the landslide hit but their fate was unclear.
Ha Giang province is a popular spot for motorcycle tours for foreign tourists.
The rainy season from June to November often brings heavy flooding and landslides to northern Vietnam.
In June, three people were killed in heavy flooding in Ha Giang province.
Last year, natural disasters left 169 people dead or missing in the South-East Asian country.
