North Korea appears to have fired two missiles on Thursday in a move that comes as it has threatened to break off sputtering nuclear talks unless U.S. President Donald Trump offers up concessions by year end.

Two unidentified projectiles were fired at 4:59 p.m. from North Korea's east coast into the Sea of Japan, South Korea's Joint Chiefs of Staff said, adding that it was monitoring for more possible launches. The Joint Chiefs hasn't yet provided information on how far the projectiles flew.

Japan's Defense Ministry said that what appeared to be at least one North Korean ballistic missile landed outside of its territorial waters.
