A South Korean Defense Ministry official says North Korea has completed preparations for a missile test that could come any day.
The warning Wednesday came as Pyongyang prepared to mark the April 15 birthday of its founder Kim Il Sung, historically a time when it seeks to draw the world's attention with dramatic displays of military power.
In Pyongyang, however, the focus was more on beautifying the city ahead of the nation's biggest holiday. Soldiers hammered away on construction projects and gardeners got down on their knees to plant flowers and trees.
The official in Seoul said the North's military is capable of conducting multiple missile launches involving Scud and medium-range Rodong missiles, as well as a missile transported to the east coast recently.
He spoke on condition of anonymity.
