HANOI: A weekend flash flood in Vietnam’s mountainous north killed five people, authorities said Tuesday, while another person remains missing after the deluge.

Heavy rains triggering flash floods were reported Saturday night in Son La province, destroying 22 houses, damaging scores more and forcing dozens of families to evacuate, the agriculture ministry said Tuesday.

Three bodies were recovered on Monday, a ministry statement said, adding to two others already found dead in the aftermath, with the search for another person still continuing.

More than 445 acres (180 hectares) of crops and 2,600 cattle and poultry were also swept away.

Vietnam is prone to tropical storms, which often cause deadly flash floods and landslides.
