U.S. and North Korean negotiators are meeting this weekend on the outskirts of Stockholm to discuss Pyongyang's nuclear program.

The U.S. delegation is reportedly led by U.S. special representative to North Korea Stephen Biegun, who was expected to meet with Kim Myong Gil, North Korea’s chief negotiator.

Despite coming to the table for talks, North Korea on Thursday fired a short- to medium-range ballistic missile from its southern Wonsan Bay that landed in the Sea of Japan.

Pentagon spokesman Jonathan Hoffman, at the time, called the missile launch "unnecessarily provocative and not helpful in an effort to get the North Koreans back on a diplomatic path."
