Demonstrations across Iran, initially sparked by economic hardship and the sharp fall of the national currency, continued for a third day on Tuesday, drawing in university students as authorities deployed force and made multiple arrests. Protests spread across Iran on Tuesday, with universities and commercial districts emerging as key hubs amid a widening strike by shopkeepers in Tehran and other cities. Human rights and student groups said at least 11 protesters were arrested near Tehran's Shoush Square. Five students were also detained at universities in the capital, four of whom were later released.
