North Korea has confirmed for the first time that it had deployed troops to Russia, with its state news agency KCNA reporting Pyongyang's soldiers helped Moscow reclaim territory under Ukrainian control in the Russian border region of Kursk.
The admission comes just days after Moscow confirmed the North's participation, while Russian President Vladimir Putin on Monday heralded the "feat" of Pyongyang's troops.
South Korean and Western intelligence agencies have long reported that Pyongyang sent more than 10,000 soldiers to help in Kursk last year.
Mutual defence treaty
North Korean forces "participated in the operations for liberating the Kursk areas", Pyongyang's Central Military Commission said in the KCNA report.
North Korean leader Kim Jong Un's decision to deploy the troops, it said, was in accordance with a mutual defence treaty Kim signed with Putin in 2024.
"They who fought for justice are all heroes and representatives of the honour of the motherland," Kim said, according to KCNA.
Kim added that a monument to the "battle feats" would soon be built in the capital, and referred to "the tombstones of the fallen soldiers", publicly confirming that North Korean troops had been killed in combat.
Putin's praise
Russia's president praised Moscow's "Korean friends" for their backing in Kursk.
"We appreciate it a lot and are deeply grateful to comrade Kim Jong Un personally... and the North Korean people," the Kremlin cited Putin as saying.
Russian Chief of Staff Valery Gerasimov on Saturday said North Korean soldiers "provided significant assistance in defeating the group of Ukrainian armed forces", but Ukrainian President Volodymyr Zelenskyy said on Sunday his military was still fighting in Kursk.
Victory Day celebrations
"The question now is whether Kim Jong Un will attend Russia's Victory Day celebrations on May 9," said Lim Eul-chul, a professor at Seoul's Institute for Far Eastern Studies.
Russia has pledged to hold its largest-ever Victory Day commemorations to mark 80 years since the defeat of Nazi Germany, featuring a massive military parade and an address from Putin.
"While the likelihood of Kim attending the event appears relatively low, it cannot be entirely ruled out," Lim said.
