The festival will wrap up on September 28, IRNA reported.
On Friday, Korea Times wrote that tens of films from Iran, Russia and China will be on screen in the festival.
During the festival, there will be competitions for the best feature, documentary as well as short and animated films.
The event also features special screenings, information screenings and film exchange meetings.
The 10-day festival — which pursues the ideals of independence, peace and friendship — will contribute to bolstering exchanges and expansion of cooperation between progressive filmmakers in the world, said a North Korean cultural official addressing the opening ceremony.
The biennial festival was first held in 1987 as a cultural event participated solely by developing countries. It has, however, turned cosmopolitan in recent years.
