Rains caused flooding that killed three people in Russia’s Dagestan republic on Monday.
The emergencies ministry said water levels rose and covered streets as well as homes in the Caucasus mountains area.
Two people died, one of them a child, when the flood swept across a highway and overturned two cars.
A third person lost their life in a landslide.
In the regional capital Makhachkala an apartment building partly collapsed.
Local authorities stopped some water filtration plants after power cuts struck the region.
Officials evacuated 4,000 people from the affected zones.
Thousands of rescuers continue work on the ground because more rain is expected.
Dagestan saw similar flooding only last week.
That earlier event brought power cuts across the area and forced the authorities to declare a state of emergency.
