Heavy rains started on Friday. The surging waters caused rivers to burst their banks and swept away cars and flooded houses in the provinces of East and West Azarbaijan, Kurdistan and Ardabil.

Eighteen villagers in Chenar, near the town of Ajabshir, East Azarbaijan, were also killed and two remain missing, he said.
According to the official, 12 houses were completely destroyed in the village, too.
In Kurdistan, one person lost his life in the deluge in the city of Baneh and 4 were killed in landslides in the town of Saqqez, the official stated.
Meanwhile, search and rescue operations continue in the areas hit by the floods, and military and law enforcement forces have been asked to assist.
