North Koreans are celebrating the 101st anniversary of the birth of Kim Il Sung, the founder of the Stalinist state.
On the most important holiday on the North Korean calendar, there was no military parade Monday, and no signs that any large-scale festivities were planned.
Although South Korea was on alert for any provocation to mark the day, the North did not test a ballistic missile or even a short-range rocket, as had been widely anticipated.
Concern about the possibility of such tests spread last week when South Korean authorities said they had seen North Korea moving mobile missile launchers on its east coast.
Kim Il Sung died in 1994.
