At least 80 people have been killed and 30 others are missing in floods that have wreaked havoc across Iran for more than a week, state media reported Saturday. 

Since the start of the Iranian month of Mordad on July 23, "59 people died and 30 are still missing in the incidents caused by recent floods," Yaghoub Soleimani, secretary-general of the Red Crescent Society, was quoted as saying by state news agency IRNA. 

That is in addition to flash floods caused by heavy rains in the normally dry southern province of Fars that left at least 22 people dead just before the start of Mordad. 

Soleimani noted that 60 cities, 140 towns and more than 500 villages across the country of around 83 million people have been affected by the inundations. 

Tehran province is the hardest-hit with 35 deaths. Nearby Mazandaran province has the highest number of missing people at 20, a list published by the Red Crescent showed.
