The South Korean military said it detected a North Korean short-range missile launch, the latest in a series of tests by the nuclear-armed country that have raised tensions with its neighbors in Asia and in the US.
South Korea scrambled F-35 fighter jets after North Korea flew warplanes near their border. According to the South Korean military, the aircraft from the North flew as close as 7 miles from the border.
In the past week, North Korea flew military aircraft near the border. Fighter jets and bomber flew close to the border last week.
The Pentagon said that it was aware of the latest missile launch by North Korea.
The event does not pose an immediate threat to U.S. personnel or territory, according to the U.S. Indopacific Command.
The United States' commitment to the defense of the Republic of Korea and Japan remains ironclad.
The latest missile launch by North Korea is in violation of several UN Security Council Resolutions, according to the State Department.
The State Department spokesman said that the Democratic People's Republic of Korea refused to engage.
Less than 24 hours later, North Korea said it test-fired a cruise missile. On October 3 and October 5, missiles were fired.
The first missile test over Japan in five years was followed by a volley of missiles from the U.S. and South Korea. Four missiles were fired into the waters off the east coast of the Korean Peninsula, according to the Pentagon.
South Korea says that North Korea has fired a missile into the sea.
The state of North Korea has provoked the ire of world leaders by conducting its most powerful nuclear test, launching its first-ever intercontinental missile and threatening to send missiles into the waters near Guam.
More than 100 missiles and four nuclear weapons tests have been conducted by Kim since 2011.
North Korea has tested more than 35 missiles this year.
