A pair of American B-1B strategic bombers took part in a joint U.S.-South Korean military exercise on Thursday, amid mounting tensions on the Korean Peninsula.
The two aircraft flew from the U.S. territory of Guam, and joined other American warplanes for the drill, including the F-22 and F-35 stealth fighter jets.
This comes just one week after North Korea test-fired a long-range rocket, which it claims is capable of reaching the continental United States.
China's military also held a series of live-fire exercises, seemingly in response to Seoul and Washington's joint drills.
According to Hong Kong's Oriental Daily News, Beijing is making preparations for a worst-case scenario, including the construction of camps to hold North Korean refugees, in case of a full-blown conflict.
