"Our Air Force plans to hold a joint drill with two B-1Bs in the sky of the Korean Peninsula today," the officer told reporters, as quoted by Yonhap news agency.
Kim added that the bombers would fly over Korea for a few hours with two South Korean F-15K fighter jets, in what he described as a regularly conducted training.
The training will take place against the backdrop of Otto Warmbier's death. On June 13, Warmbier was returned to the United States from North Korea in a coma after being held in that country for more than a year. Warmbier, a student, spent 17 months in detention for anti-state actions because he attempted to steal a poster from his hotel. On Monday, the student's family confirmed that Warmbier has died at his home in Ohio.
