DUBAI (Reuters) -Protests raged for a fourth straight day across Iran on Tuesday and authorities said three people had been killed during unrest over the death of a young woman in police custody.

The death last week of 22-year-old Mahsa Amini who was arrested by morality police for "unsuitable attire" unleashed a flood of simmering anger over numerous issues including rights, security and an economy reeling from international sanctions.
