The US military believes that the upcoming US-South Korean naval drills may push North Korea toward new actions.
A US satellite took pictures of ballistic missiles mounted on launchers being transported out of a hangar to somewhere near Pyongyang and North Pyongan Province, according to the report.
A source said US military officials believe this could indicate preparation for a launch of a missile comparable to the Hwasong-14 intercontinental ballistic missile (ICBM) or Hwasong-12 intermediate-range ballistic missile (IRBM). Another scenario could be a launch of the new Hwasong-13 solid engine missile that has a longer range than the Hwasong-14.
"The North may carry out a simultaneous launch of an ICBM and IRBM within a few days, in protest against the US show of military might," another source told the newspaper.
