North Korea says it is examining its operational plans for attacking Guam to contain U.S. bases there.
The army said in a statement distributed Wednesday by the state-run news agency that it is studying a plan to create an "enveloping fire" in areas around Guam with medium- to long-range ballistic missiles. The U.S. territory is home to Andersen Air Force Base.
The statement says the move is in response to a recent U.S. ICBM test.
It comes as President Donald Trump says North Korea "will be met with fire and fury like the world has never seen" if it makes any more threats to the U.S.

Republican Sen. John McCain says "great leaders" don't threaten foes unless they're ready to act - and he's not certain President Donald Trump is ready to act against North Korea.
McCain, who heads the Armed Services Committee, made the comments Tuesday in an interview on KTAR News in Phoenix.
He is responding to Trump's warning that North Korea could face "fire and fury" if it threatens the United States after a new report said U.S. intelligence officials believe Pyongyang has successfully produced a nuclear warhead that can fit inside its missiles.
McCain says he takes exception to Trump's comments "because you got to be sure you can do what you say you're going to do."

The Washington Post is reporting that U.S. intelligence officials assess that North Korea has successfully produced a miniaturized nuclear warhead that can fit inside its missiles.
That would mean North Korea has passed a crucial threshold on the path to becoming a full-fledged nuclear power.
The Post story, citing unnamed U.S. intelligence officials, said the confidential analysis was completed last month by the U.S. Defense Intelligence Agency.
Officials at the agency would not comment Tuesday. The Office of the Director of National Intelligence could not immediately be reached for comment.
Separately, Japan's defense ministry assessed in a report Tuesday that it is possible that North Korea has achieved the miniaturization of nuclear weapons and has developed nuclear warheads.
