The fire destroyed tens of hectares of forests and pasture.
The cause of the blaze is unknown. There are no reports of casualties as a result of the fire.
Kūh-e Bīsotūn is of high importance archeologically and an inscription engraved on a wall in the mountain is a world heritage site.
The inscription is unique, being the only known monumental text of the Achaemenids to document a specific historic event, that of the re-establishment of the empire by the great Persian king, Darius I.
This is the first cuneiform writing to be deciphered in the 19th century.
