North Korea appears to have held a low-key military parade, a day ahead of the Winter Olympics, South Korean media said.
The annual event is usually held in April, but Pyongyang hit back at US criticism of its decision to bring it forward.
State TV began showing patriotic films in what appeared to be a prelude to a live broadcast.
But reports later surfaced that it had already taken place.
“It seems that North Korea opened the parade at 10:30 a.m. (Seoul time),” anonymous government sources told South Korea’s Yonhap news agency.
On Thursday, North Korea said it has no intention of meeting US officials during the Games, according to the North’s official KCNA news agency.
South Korean government officials had said last month that some 13,000 troops and 200 pieces of equipment had been spotted near an airport in Pyongyang in what appeared to be a rehearsal for the parade.
Experts say North Korea was expected to showcase its long-range missiles.
