According to local authorities, the downpour lasted about 30 minutes.

At around 4:00 pm, the 1.5-meter-high retaining wall behind a makeshift house in an alley on Hung Vuong Street, Xuan Truong Ward suddenly gave way, sending soil and rocks into the nearby Tay Ho café and burying two customers.

Both victims died at the scene.

Tran Hung Son, chairman of the Xuan Truong Ward administration, said the area has been cordoned off to prevent further danger, and the victims’ families are being supported with funeral arrangements.

The retaining wall collapse occurred in a sparsely populated area far from main roads.

The downpour also inundated parts of Da Lat, forcing the evacuation of hundreds of residents.

In Alley 28 on Lu Gia Street in Lam Vien Ward, water from a nearby stream rose to nearly one meter, isolating dozens of households.

Elderly residents and children were trapped inside until rescue forces reached them.

Officials said about 40 households in the area have been temporarily relocated to three safe locations until floodwaters recede.

Several streets, including Xo Viet Nghe Tinh, Phan Dinh Phung, and Tran Quoc Toan, also experienced flooding.

Authorities have urged residents to avoid traveling through inundated areas and to follow weather advisories.
