The order was announced by Curtis Scaparrotti, the head of US military deployment in South Korea, who was visiting the Osan airbase, run by Washington and Seoul.
Scaparrotti was touring the base, which is 55 kilometers south of the capital Seoul, together with South Korean Joint Chiefs of Staff Chairman General Lee Sun-jin.
“Following the North’s recent nuclear test, its military is highly likely to push ahead with further sudden provocations,” Lee said, as cited by the Yonhap news agency.
The base inspection came a day after Washington deployed a strategic B-52 bomber on a low altitude demonstration flight over South Korea, to flex the alliance’s muscle and indicate determination following North Korea’s latest nuclear test.
