South Korean footballers were left dumbfounded at an international tournament in Indonesia when organisers played the North's anthem instead. Ahead of an AFC under-19 Championship qualifier against Jordan at the Patriot Candrabhaga Stadium on the outskirts of Jakarta, the South's team lined up with their hands on their hearts. But instead of Seoul's hymn-like anthem "Aegukga", North Korea's national tune blared out, leaving them stony-faced and silent.

The South's coaching staff told officials of the mistake, and while the correct song was then played, they protested after the game on Monday evening. Seoul's football authorities said Tuesday they will file a formal complaint with the Asian Football Confederation (AFC). "This is the first time that the North Korean anthem was played instead of Aegukga at any official international match for any level of the national football team," the Korea Football Association said in a statement.
