Organisers apologised after playing North Korea's national anthem for South Korea's men's hockey team at the Asian Games in Japan. South Korea, who beat Bangladesh 5-0, looked confused as the wrong anthem played. Yonhap reported Bangladesh's anthem followed before South Korea's actual anthem. An announcer apologised.

"This is a really serious problem. When we protested, they said, 'We're sorry. It wasn't that it wasn't prepared; there was a mistake on the part of those responsible for playing it'," South Korea coach Min Tae-seok said. "But this is something that simply should never happen."

North Korea's anthem and symbols are banned in South Korea. The countries are still technically at war after the 1950-53 conflict ended without a peace treaty.

The build-up to the Asian Games, starting Saturday, saw complaints about accommodation. A South Korea basketball player posted a video of a leaking pipe and soaked floor, captioning: "Please help me." Some teams were stranded at the airport for up to six hours. Field hockey started Friday and runs until 3 October.
