North Korea has opened a memorial museum in Pyongyang for its soldiers killed while fighting alongside Russian forces in the war in Ukraine, in the clearest sign yet of how central the conflict has become to the growing alliance.

The inaugural ceremony at the Memorial Museum of Combat Feats at the Overseas Military Operations was held on Sunday. It also marked the first anniversary of what the two countries describe as the end of an operation to “liberate” Russia’s Kursk border region from a Ukrainian incursion, the state-run Korean Central News Agency (KCNA) reported on Monday.

KCNA said North Korea’s leader Kim Jong Un attended the event along with senior Russian officials, including State Duma Chairman Vyacheslav Volodin and Defence Minister Andrei Belousov.

South Korea’s intelligence agency has estimated that North Korea deployed about 15,000 soldiers to fight for Russia in the Kursk region, and that about 2,000 of them were killed. Moscow and Pyongyang have not disclosed any figures.

During the ceremony, Kim sprinkled earth over the remains of one soldier and laid flowers for others whose bodies had been placed in a mortuary, according to KCNA. Kim and the Russian officials then signed a guestbook at the newly opened museum.

In his speech, Kim said the fallen North Korean troops would remain “a symbol of the Korean people’s heroism” and would support “a victorious march by the Korean and Russian people”.

He accused the United States and its allies of pursuing a “hegemonic plot and military adventurism” on the Russia-Ukraine front, praising Russian and North Korean forces for thwarting those efforts.

Meeting Belousov separately, Kim pledged full support for Russia’s policy of defending its sovereignty and security interests, KCNA said.

Russia’s TASS news agency quoted Belousov as saying that Moscow is ready to sign a military cooperation plan with Pyongyang covering 2027-31.

In a letter read by Volodin, Russian President Vladimir Putin said the new museum would be “a clear symbol of the friendship and solidarity” between the two countries and pledged to further strengthen their “comprehensive strategic partnership”.

Since Russia’s full-scale invasion of Ukraine in 2022, Kim has tilted his foreign policy decisively towards Moscow, supplying troops and conventional weapons in exchange, analysts say, for economic support and possibly sensitive technologies.

Officials in South Korea, the US and allied countries fear Russia could transfer advanced know-how to Pyongyang that would boost its nuclear and missile programmes.

Military experts say North Korean troops initially suffered heavy losses in Kursk due to their lack of combat experience and unfamiliarity with the terrain, making them vulnerable to Ukrainian drone and artillery fire.

But Ukrainian military and intelligence officials have assessed that the North Koreans later gained crucial battlefield experience and became central to Russia’s efforts to overwhelm Ukrainian forces by deploying large numbers of soldiers in the region.

Multiple ballistic missiles fired from eastern Sinpo area in seventh such test this year.

North Korea has launched multiple ballistic missiles towards the sea off its eastern coast, according to South Korea and Japan.

The incident on Sunday marked North Korea’s seventh ⁠ballistic missile launch this year and its fourth in April.

The missiles were fired near the city of Sinpo on North Korea’s east coast at about 6:10am on Sunday (21:10 GMT, Saturday), South Korea’s military said in a statement. It added that South Korea had bolstered its surveillance posture and was closely exchanging information with the United States and Japan.

Japan’s ⁠government posted on social media that the ballistic missiles were believed to have fallen near the east coast of the Korean Peninsula. No incursion into Japan’s exclusive economic zone was confirmed.

South Korea’s presidential office said it has held an emergency security meeting, according to media reports.

Such tests violate United Nations Security Council resolutions against North Korea’s missile programme. The diplomatically isolated country rejects the UN ban and says it infringes on its sovereign right to self-defence.

The launches come as China and the US prepare for a summit in mid-May, ⁠in which Chinese President ⁠Xi Jinping and his US counterpart, Donald Trump, are expected to discuss North Korea.

North Korea has made “very serious” advances in its ability to turn out nuclear weapons, with the probable addition of a new uranium enrichment facility, ‌International Atomic Energy Agency chief Rafael Grossi said on Wednesday.

Late last month, North Korean leader Kim Jong Un said his country’s status as a nuclear-armed ‌state ‌was irreversible and that expanding a “self-defensive nuclear deterrent” was essential to national security.
