Intense rains since early October have caused floods and mudslides that have killed at least 64 people in central Vietnam, with more heavy rainfall expected over the next few days.
The landslide hit the barracks of a unit of Vietnam's 4th Military Region, the government said in a statement on its website, days after another landslide killed 13 people, mostly soldiers, in the neighboring province of Thua Thien Hue.
"We had another sleepless night," a visibly emotional Phan Van Giang, Vietnam's deputy defense minister, told reporters on Sunday.
State media reports said on Sunday water at rivers in Quang Tri province rose to the highest levels in more than 20 years.
In Thua Thien Hue province, rescuers continued to battle driving rain as they searched for at least 15 construction workers missing and feared dead after a landslide at the start of the week in a mountainous area.
Heavy rain of up to 600 millimeters will continue in parts of central Vietnam until Wednesday, Vietnam's weather agency said on Sunday.
