The sound of apparent gunshots and explosions echoed early on Monday through the streets of a western Iranian city at the epicentre of protests over the death of a 22-year-old woman, with at least one man reportedly killed by security forces in a village nearby, activists said.

The incidents come as demonstrations rage on in cities, towns and villages across Iran over the September 16 death of Mahsa Amini, who died days after being detained by the morality police in Tehran.
