WASHINGTON U.S. intelligence officials say North Korea s nuclear test yielded an explosion of approximately several kilotons.

In a statement Tuesday, the Office of the Director of National Intelligence said North Korea probably conducted an underground nuclear explosion in the vicinity of P unggye. It said the explosion yield was approximately several kilotons and that analysis of the event is continuing.

South Korea s Defense Ministry said it detected an estimated explosive yield of 6-7 kilotons.

President Barack Obama called North Korea s action highly provocative and said it threatens U.S. security and international peace.
