At least 30 people were killed in a landslide that buried several houses in a Myanmar town, according to authorities on Saturday.

As the mountainside of Ma-Lat mountain collapsed due to heavy rain in Paung Township, Mon State, the road section on Yangon-Mawlamyaung Highway was covered with soil about 2-ft high.

One of the survivors, a 70-year-old woman said that she lost 13 relatives in this “unprecedented” natural disaster.

“This is the very first time, I’ve never seen anything like this before in my life,” she said.

Hundreds of residents of nearby villages have been left isolated and await aid as heaps of mud blocked roads and paths.

“When we arrived at the accident, houses and vehicles collapsed under the soil. We rescued people and sent them to the nearby clinic and hospital. At present, we don’t know exactly how many people are missing. I think, some victims may be floating in the heavy rain,” said Nay Win from Natsingone village.

The administrator from Ye Pyar Gone village also said that about 10 houses collapsed under the soil and some vehicles were blown out. Seven bodies had already been found.

According to the UN, the intense monsoon rains ravaging the region this week have forced nearly 38,000 people to temporarily abandon their homes.
