South Korea has carried out a missile drill meant to "strongly warn" North Korea over its sixth nuclear test, military officials said.
The military training involved long-range air-to-surface missiles and ballistic missiles, South Korea's joint chiefs of staff said in a statement early on Monday.
The drill was carried out by only the Korean military, but more are being prepared with the US forces in South Korea, the statement said.

According to state news agency Yonhap, "the training came in response to the North's sixth nuclear test ... and involved the country's Hyunmoo ballistic missile and the F-15K fighter jets".
The military added that the target of the exercise was set considering the distance to where the North's test site was and the drill was aimed at practicing precision strikes and cutting off reinforcements.
North Korea conducted its sixth and most powerful nuclear test on Sunday, with what it said was an advanced hydrogen bomb for a long-range missile.
The test marks a dramatic escalation of Pyongyang's standoff with the United States and its allies.
The official Korean Central News Agency (KCNA) called the test a "perfect success".
'War should not be repeated'
Following the test, US President Donald Trump criticised South Korea for what he called its "talk of appeasement".
