WASHINGTON (Reuters) - U.S. spy satellites have detected renewed activity at the North Korean factory that produced the country’s first intercontinental ballistic missiles capable of reaching the United States, a senior U.S. official said on Monday, in the midst of talks to compel Pyongyang to give up its nuclear arms.

Photos and infrared imaging indicate vehicles moving in and out of the facility at Sanumdong, but do not show how advanced any missile construction might be, the official told Reuters on condition of anonymity because the intelligence is classified.
