An explosion occurred at an Iranian chemical plant Monday, Iranian media reported.
The blast allegedly occurred at a gas condensate plant in the Kavian Fariman industrial zone in the Razavi Khorasan Province in eastern Iran. The explosion was caused by a fire which broke out at one of the gas tanks.
Firefighters were able to put out the blaze before it spread to other tanks and caused additional explosions. The cause of the fire is under investigation.
The incident is the latest in a series of explosions which have rocked Iran in recent weeks.
