BEIJING, Feb. 13 -- North and South Korea are at loggerheads over which national anthems and flags will be used when the two countries meet in a World Cup qualifier next month, an official said Tuesday.

"North Korea wants us to use a joint Korean flag and anthem ... instead of allowing us to use our own," said You Young-cheul, spokesman for South Korea's soccer federation.

According to FIFA rules, the flags and national anthems of both participating countries must be used in international matches, You added.

The two Koreas will try to resolve the issue themselves but may have to turn to FIFA for help, You said.
