North Korea fires artillery into sea as South Korea, U.S. pledge cooperation

North Korea fired multiple missiles into the sea on Thursday, including a possible failed intercontinental ballistic missile (ICBM), prompting the United States and South Korea to extend air drills that have angered Pyongyang.

Beginning shortly before midnight on Thursday, South Korea’s military said it had detected more than 80 artillery rounds fired into the sea by North Korea, in what it says is a violation of a 2018 inter-Korean agreement.

The South issued a warning communication to the North over the firing, the South Korean Ministry of Defence said in a statement.

Meeting in Washington, U.S. Defense Secretary Lloyd Austin and South Korean Defense Minister Lee Jong-sup pledged to seek new measures to demonstrate the alliance’s”determination and capabilities” following repeated North Korean provocations, according to a joint statement between the two countries.

Tensions have been rising as North Korea has conducted a record number of missile launches this year, including at least 23 on Wednesday alone and the ICBM launch on Thursday. South Korea and the United States also say that North Korea has completed technical preparation to test a nuclear device at any time, in what would be its first nuclear test since 2017.

Pyongyang, meanwhile, has condemned allied military drills.

On Thursday, Pak Jong Chon, secretary of the Central Committee of North Korea’s ruling Workers’ Party,said Washington and Seoul had made a very dangerous decision by extending the exercises, and were “shoving” the situation out of control.

“The United States and South Korea will find that they have made a terrible mistake that cannot be reversed,” said Pak.

Diplomats said Washington had asked the U.N. Security Council to convene publicly on North Korea on Friday, a request backed by other council members Britain, France, Albania, Ireland and Norway.

North Korea has long been banned from conducting nuclear tests and ballistic missile launches by the Security Council, which has strengthened sanctions on Pyongyang over the years to try to cut off funding for those programs.

However, in recent years the 15-member council has been split on how to deal with North Korea and in May, China and Russia vetoed a U.S.-led push to impose more U.N. sanctions in response to North Korean missile launches.
