Iranian students take part in a rally marking the 37th anniversary of taking over the U.S. embassy by a group of Iranian students in Tehran, capital of Iran, on Nov. 3, 2016. Tens of thousands of Iranians held nationwide demonstrations on Thursday to mark the 37th anniversary of the seizure of the U.S. embassy in Tehran. Since the 1979 takeover of the U.S. mission by Iranian students, Iranians have been celebrating the occasion every year by holding rallies on the anniversary and marking it as the "National Day against the Global Arrogance."
