North Korea on Monday fired four banned ballistic missiles that flew about 1,000 kilometers (620 miles), with three of them landing in Japan's exclusive economic zone, South Korean and Japanese officials said, in an apparent reaction to huge military drills by Washington and Seoul that Pyongyang insists are an invasion rehearsal.

North Korea's latest volley of missile tests has added to pressure on a preoccupied Trump administration to identify how it will counter leader Kim Jong Un's weapons development.

North Korea's march toward having a nuclear-tipped missile that could reach the U.S. mainland is among the pressing national security priorities President Donald Trump faces. He has vowed it "won't happen" but has yet to articulate a strategy to stop it.

A wide array of options are on the table, but aggressive behavior by Pyongyang in response to U.S.-South Korean military drills that began last week could further shrink chances for diplomatic engagement.

Upheaval in the administration has added to uncertainty in foreign capitals about how a new president lacking experience in government would handle a security crisis should one unfold.
