This was done as a sign of solidarity with partners from Iran, where a five-day mourning period has begun in connection with the death of the country’s President and his companions in a plane crash. On Tuesday, May 21, flags were lowered on all flagpoles of the Empress Catherine II St. Petersburg Mining University. In addition, a tripod with a portrait of Ibrahim Raisi was set up in the courtyard of the historical building, to which students, graduate students and employees of the higher educational institution carried flowers throughout the day.
