EIELSON AIR FORCE BASE, Alaska, (Reuters) - The United States will soon present a timeline to North Korea with "specific asks" of Pyongyang after a historic summit between U.S. President Donald Trump and North Korean leader Kim Jong Un, a senior U.S. defence official said.

The official, who spoke to a small group of reporters ahead of a trip to Asia this week by Defense Secretary Jim Mattis, did not specify details but suggested that the timeline would be rapid enough to make clear Pyongyang's level of commitment.
