Schoolgirls chanted slogans, workers went on strike and protesters clashed violently with security forces across Iran on Saturday, as demonstrations over the death of Mahsa Amini entered a fourth week.

Iran has repeatedly accused outside forces of stirring up the protests, and last week announced that nine foreign nationals -- including from France, Germany, Italy, Poland and the Netherlands -- had been arrested.
