Story highlights U.S. Strategic Command: One missile exploded on launch, another flew into sea

One missile exploded on launch, another flew into sea Rodong missiles were fired, U.S. and South Korea say

Seoul, South Korea (CNN) North Korea fired two ballistic missiles Wednesday morning -- including one into the Sea of Japan -- in the country's latest defiance of U.N. Security Council resolutions, U.S. and South Korean authorities said.

The missiles, presumed to be No Dong, or Rodong, intermediate range ballistic ones, were fired simultaneously from the country's west, the U.S. Strategic Command said.

One exploded after launch, the Strategic Command said. The other flew about 621 miles (1,000 kilometers) over North Korea and into the Sea of Japan, the South Korean Joint Chiefs of Staff said.

The firing drew international condemnation. Japan said the farthest-flying missile landed about 155 miles (250 kilometers) west of the Oga Peninsula inside its exclusive economic zone -- an area of the sea where a country claims maritime rights to resources such as fish, oil and gas.
