Two people were killed overnight in the town of Dorud in western Iran as protests spread across the country, the province's deputy governor confirmed on Sunday. 

"On Saturday evening, there was an illegal protest in Dorud and a number of people took to the streets responding to calls from hostile groups, leading to clashes," Lorestan province deputy governor Habibollah Khojastehpour told state television.

"Unfortunately in these clashes two citizens from Dorud were killed."

Khojastehpour did not explain the killings but said security forces had not fired on the crowd.
