At least 23 people have been killed -- and more than 500 reportedly detained -- since anti-government protests erupted across Iran late last week.

Axar.az reports citing Turkish media.

According to local media outlets and state officials, four people were killed in Iran’s Lorestan province; two in Khuzestan province; three in Hamadan province; and 14 in Isfahan province, including a police officer.

While state officials say at least 500 others have been detained, unofficial sources put the number much higher.

On Thursday, thousands of people hit the streets in Iran’s northeastern cities of Mashhad and Kashmar to protest rising inflation and perceived government mismanagement, according to local media reports.

Thursday's protests were followed by a number of pro-government protests on Saturday.

On Sunday, President Hassan Rouhani warned citizens against joining the protests, which have since spread to a number of other urban centers.

"We must avoid putting the country in a situation that our enemies can take advantage of," Rouhani said after a cabinet meeting.
