The 2014 Asian Games opened in Incheon, South Korea on September 19 with 14,000 athletes and officials participating from 45 countries.
The ceremony began with the march of the athletes followed by a message from Olympic chief Thomas Bach, before South Korean President Park Geun-hye declared the games officially open.
The Iranian caravan consists of 276 athletes competing in 22 disciplines.
