At least ten people have been killed and multiple others wounded during a fourth night of unrest in Iran.
Iranian state TV reported the figure on Monday morning but gave no further details on the deaths.
Two people were shot dead in the southwestern town of Izeh while another two died in Dorud after being run over by a stolen fire truck, local news agencies reported.
Elsewhere there were unconfirmed reports that three people were shot dead after security forces opened fire on protesters in Isfahan.

The deaths in Izeh were confirmed by local politician Hedayatollah Khademi, who said it was unclear whether they were killed by police or other demonstrators.

The shooting in Isfahan was reported by several prominent Twitter personalities including Amichai Stein, foreign affairs correspondent for the Israeli public broadcasting corporation, but could not be independently verified.

Protesters in the small northwestern town of Takestan torched a school for clergy and government buildings, the ILNA news agency said, while the state broadcaster said two people had died in Dorud after crashing a stolen fire engine.
There were also reports of protests in the cities of Izeh (southwest), Kermanshah and Khorramabad (west), Shahinshahr (northwest) and Zanjan (north).
Verifying reports remained challenging due to travel restrictions and sporadic blocks on mobile Internet and popular social media sites including Telegram and Instagram.
The protests began as demonstrations against economic conditions in second city Mashhad on Thursday but quickly turned against the Islamic regime as a whole, with thousands marching in towns across Iran to chants of 'Death to the dictator'.
'The people are absolutely free in expressing their criticisms and even protests,' Rouhani said in a message on the state broadcaster.
