The United States, meanwhile, staged another show of force meant to deter any North Korean aggression by flying two B-1B supersonic bombers Tuesday night from an air base in the USA territory of Guam to the South for drills with South Korean fighter jets.
The two US Air Force B-1B bombers were joined by two F-15K fighters from the South Korean military after leaving their base in Guam, South Korea's Joint Chiefs of Staff said in a statement on Wednesday.
Officials feared the rogue nation would test another missile or nuclear bomb on Monday or Tuesday as North Korean citizens celebrated the 11th anniversary of the country's first nuclear test and the foundation of the ruling Worker's Party of Korea.
North Korea has launched two missiles over Japan and conducted its sixth and biggest nuclear test in recent weeks in defiance of U.N. sanctions as it races toward its goal of developing a nuclear-tipped missile capable of hitting the United States.
"Through the practice this time, South Korean and US air forces showed off the allies' resolve for strong retaliation against North Korea's nuclear and missile threats", it added.
The US bombers had taken off from the Andersen Air Force Base in Guam.
The Air Force said Tuesday's overflight demonstrated how USA military forces "are always ready to defend the American homeland and how the US stands resolutely with Japan and [South Korea] to honor their unshakeable alliance commitments to safeguard security and stability".

Northbound lanes of the 241 to the 91 freeway, and the east and west off-ramps at Gypsum Canyon Road, have also been shut down. Since Anaheim Hills is a heavily equestrian area, many residents have horses, and the fast-moving fire has posed challenges.
The Pentagon also declined to comment specifically on reports of the potential breach, but spokesman Col. Robert Manning said on Tuesday that the U.S. is "confident in the security of our operations plans and our ability to deal with any threat from North Korea". The US has repeatedly ruled out negotiations with North Korea.
In his speech before the United Nations General Assembly in September, Trump said the U.S. will "totally destroy" North Korea if it pushes ahead with its development of nuclear weapons and intercontinental ballistic missiles.
A ministry spokesman declined to confirm the report, citing intelligence matters. Trump's Director of the Office of Management and Budget, Mick Mulvaney, later said that the president was telegraphing with the statement that "military options are on the table".
Tensions over North Korea's weapons programme have soared in recent months with Pyongyang launching a flurry of missiles and conducting its sixth and most powerful nuclear test in defiance of multiple sets of United Nations sanctions. China's influential Global Times tabloid expressed alarm at how far the rhetoric on both sides had gone and how it had increased the risk of a "fatal misjudgment". A Chinese Foreign Ministry spokesperson expressed hope that the relevant countries "will not engage in words or deeds that provoke one another or raise tensions", while a Kremlin spokesperson stressed that [Moscow] has "demanded that the countries involved [in the North Korean nuclear issue] exercise restraint and avoid measures that exacerbate the situation". "This positive process is worth a try", the paper said in an editorial late on Tuesday.
The secretive state has been suspected of carrying out cyber attacks on South Korean electric utilities as well as on other government and financial institutions.
Speaking during a parliamentary audit Thursday, Foreign Minister Kang Kyung-wha said, "We will beef up our leading role to generate an environment in which denuclearization talks can resume".
