Rocks rained down on the barracks of a military station in Quang Tri province, with 22 soldiers believed to have been buried underneath thick mud, an official government website said.

Last year Vietnam signed a 10-year deal with Formula One to host an event state media said would cost the country $60 million per year.

More than a hundred thousand homes have been submerged in the floods and nearly 46,000 people evacuated, Vietnam's disaster management authority said.
