Japan's prime minister says North Korea has fired what is believed to be a missile and it may have landed in the sea off Japan.
Prime Minister Shinzo Abe told reporters that officials are analyzing the apparent launch and that he has called a meeting of the National Security Council.
In Washington, a Pentagon spokesman, Navy Capt. Jeff Davis, confirmed that a launch of a ballistic missile from North Korea had been detected.
He said, "We are assessing and will have more information soon."
