Iran evacuated more towns and villages on Saturday hit by floods after continued rain in the southwest of the country.
Residents in oil-rich southwestern province of Khuzestan were being moved to safer areas.
According to reports, authorities are recommending women and children to leave and asking men and youth to help build floodwalls to keep the water out of cities.
The floods are the worst in 70 years.
The emergency services head said, at least 70 people were killed and about 1,900 cities and villages have been affected by floods.
Around 86,000 people were moved to emergency shelters and 1,000 people airlifted by emergency helicopters to safety in recent days.
Rains are expected to end in Khuzestan by Monday.
The exceptionally heavy rains started on March 19.
The disaster has left aid agencies struggling to cope with the situation.
Iranian President Hassan Rouhani said the US sanctions on energy and banking sectors hampered aid efforts.
He said, Iran’s state budget is already stretched.
