Iran executed a protester on Thursday who was convicted of injuring a security guard with a knife and closing off a street in the capital, Tehran, the semi-official Tasnim news agency reported.

Nationwide protests that erupted after the death of 22-year-old Kurdish Iranian woman Mahsa Amini on Sept. 16 represent one of the biggest challenges to the Islamic Republic since its establishment in 1979.

The Tasnim news agency identified the person who was executed as Mohsen Shekari but gave no more details.
