MOSCOW (Sputnik) — The strategic bombers are due to arrive at the US Osan Air Base located in the city of Pyeongtaek, 43 miles south of Seoul, this week, the source told the Yonhap News Agency.
"They may stay at the US air base for several days for a possible unveiling to the public during the Osan base's opening event this weekend," the source said, as quoted by the media outlet.
Earlier on Tuesday, the North Korean state media said that Pyongyang had successfully tested a high-power rocket engine, which would allow Pyongyang boost its capabilities at space exploration.
On September 9, Pyongyang carried out a nuclear test at its northeastern nuclear test site. The nuclear experiment is believed to be the fifth and the largest since North Korea started pursuing nuclear and ballistic missile programs, drawing condemnation from the international community.
