There have been reports of overnight clashes between security forces and protesters in several locations across Iran.

Protestors have been filmed burning the Iranian flag in the western Kurdistan province. Human rights groups say security forces have used live ammunition against civilians there.

There are also reports of protests in cities and towns in several other locations.

The recent unrest was sparked after 22-year-old Mahsa Amini died days after being arrested by morality police for allegedly not complying with strict rules on head coverings.
