At least 25 people have been killed by flash floods in northwest Iran.
Authorities say at least 16 others are missing in East Azarbaijan and three other provinces.
Rescue teams have been deployed to the cities of Ajab Shir and Azarshahr to help find survivors.
The police, army and air ambulances are all involved in the rescue operation.
Red Crescent workers are assisting and providing aid.
The floods have been triggered by heavy rains which started on Friday.
The surging waters have caused rivers to burst their banks and have swept away cars and flooded houses.
