Reza Shekari scored the second of his two goals early in the second half to give Iran a 2-0 lead, but Zambia rebounded with goals in the 54th, 59th, 65th and 71st minutes. Fashion Sakala scored the first goal in Seogwipo, Enock Mwepu equalized, and Emmanuel Banda and Patson Daka added the others. Iran is in second place in Group C with three points.
