North Korea fires more than 20 missiles, one close to South

SEOUL, South Korea — North Korea fired more than 20 missiles Wednesday, including one that landed close to South Korea's waters in what President Yoon Suk-yeol said was "effectively a territorial invasion".

It also fired an artillery barrage into a maritime "buffer zone" that experts said was part of an "aggressive and threatening" response by Pyongyang to large-scale joint air drills the United States and South Korea are conducting.

One short-range ballistic missile crossed the Northern Limit Line, the de facto maritime border, prompting a rare warning for residents on the island of Ulleungdo to seek shelter in bunkers.

Seoul's military said it was the "first time since the peninsula was divided" at the end of Korean War hostilities in 1953 that a North Korean missile had landed so close to the South's territorial waters.

"President Yoon pointed out today that North Korea's provocation is an effective territorial invasion by a missile," his office said in a statement.

One of the missiles landed in waters just 57 kilometres (35 miles) east of the mainland, the military said, calling the incident "very rare and intolerable".

Pyongyang fired a total of 23 missiles including seven short-range ballistic missiles and six ground-to-air ones, Seoul's military said.

North Korea also conducted an artillery barrage, firing into a maritime "buffer-zone" set up in 2018 in a bid to reduce tensions between the two countries during an ill-fated bout of diplomacy.

The huge volley of launches were "provocations against South Korea", said Go Myong-hyun, a researcher at the Asan Institute for Policy Studies.

"I wouldn't be surprised if they lead up to a nuclear test," he added.

South Korea, for its part, said it had fired three air-to-ground missiles into the sea towards the north of the two countries' maritime boundary.

President Yoon called a meeting of the National Security Council, ordering "swift and stern measures so that North Korea's provocations pay a clear price".

South Korea closed some air routes over the East Sea, also known as the Sea of Japan, advising local airlines to detour to "ensure passenger safety in the routes to the United States and Japan".

White House national security spokesman John Kirby slammed North Korea as "reckless" for carrying out the launches.

"We... condemn these missile launches and the DPRK's reckless decision to fire a missile below the de facto maritime boundary with the Republic of Korea," Kirby said. 

European Council President Charles Michel said he was outraged by Pyongyang's "aggressive and irresponsible behaviour," while Russia called for calm. Britain also joined the chorus of condemnation of the launches.

Separately, Kirby said the United States believes North Korea is sending a significant amount of artillery ammunition to Russia for its war in Ukraine, under cover of shipments to the Middle East or Africa.

'Vigilant Storm'

Pyongyang's day of missile launches came as Seoul and Washington staged their largest-ever joint air drills, dubbed Vigilant Storm, which involved hundreds of warplanes from both sides.

Pak Jong Chon, a high-ranking North Korean official, had earlier called the drills aggressive and provocative, according to a report in state media Wednesday.

Pak said the name of the exercises harked back to Operation Desert Storm, the US-led military assault on Iraq in 1990-1991 after the invasion of Kuwait.

"If the US and South Korea attempt to use armed forces against the (Democratic People's Republic of Korea) without any fear, the special means of the DPRK's armed forces will carry out their strategic mission without delay," he said.

"The US and South Korea will have to... pay the most horrible price in history."

'Dangerous situation' 

North Korea's missile launches on Wednesday appeared to be "the most aggressive and threatening armed demonstration against the South since 2010", Cheong Seong-chang, a researcher at the Sejong Institute, told AFP.

"It is now a dangerous and unstable situation that could lead to armed conflict," he added.

In March 2010, a North Korean submarine torpedoed the South Korean naval vessel Cheonan, killing 46 sailors, including 16 who were on mandatory military service.

In November of the same year, the North shelled a South Korean border island, killing two marines -- both of them young conscripts.

Wednesday's missile tests follow a recent blitz of launches, including what the North said were tactical nuclear drills.

Washington and Seoul have repeatedly warned the launches could culminate in another nuclear test -- which would be Pyongyang's seventh.

"Pyongyang seems to have completed its most powerful deterrent. This is a serious threat," Park Won-gon, a professor at Ewha University, told AFP.

The North's latest launches came with South Korea in a period of national mourning after more than 150 people -- mostly young women in their 20s -- were killed in a crowd crush in Seoul on Saturday.

It shows "North Korea's clear priorities", Yang Moo-jin, professor at the University of North Korean Studies in Seoul, told AFP.

"Pyongyang probably thinks it has no reason to take the Itaewon tragedy into its consideration, as Seoul and Washington's largest-ever joint air drills are also happening anyway," he added.
