SEOUL, Aug. 9 (Yonhap) — Two B-1B U.S. strategic bombers trained again over Korea earlier this week, a defense official in Seoul said Wednesday.

The B-1B Lancers from Guam were deployed in the sky over the peninsula Tuesday as part of a regular combined exercise with the South’s fighter jets, the official said. The allies did not announce the mission in advance.

North Korea’s military threatened Wednesday to launch an intermediate-range ballistic missile attack on “areas near Guam” in order to contain the U.S. military’s strategic assets based on the Pacific island.
