SEOUL, South Korea (AP) — A North Korean delegation led by the head of a hugely popular girl band has arrived in South Korea to check preparations for a Northern art troupe during next month's Winter Olympics.

Seoul's Unification Ministry says the North Korean delegation crossed the borderline on Sunday inside the heavily fortified Demilitarized Zone bisecting the two Koreas.

The North first abruptly canceled the visit this weekend, just hours after proposing it through a cross-border hotline, then late Saturday announced it would go ahead.

The delegation is led by Hyon Song Wol, head of the art troupe which is to perform twice in during the Pyoengchang Olympics. She is also the leader of Pyongyang's Moranbong Band, which was hand-picked by leader Kim Jong Un.
