North Korea on Saturday condemned "aggression moves" by Washington and Seoul, vowing to take revenge as it marked the 72nd anniversary of the outbreak of the Korean War at a time of rising tension on the Korean Peninsula.
Amid concerns North Korea could be preparing to conduct its first nuclear test in five years, South Korean President Yoon Suk-yeol and US President Joe Biden agreed in May to deploy more US weapons if it was necessary to deter the North.
The North's state news agency KCNA said on Saturday a number of workers' organizations had held meetings to "vow revenge on the US imperialists," blaming the United States for starting the 1950-1953 Korean War.
The war ended in an armistice rather than a peace treaty, meaning US-led UN forces are still technically at war with North Korea.
According to the KCNA report, Pyongyang denounced Washington over what it called "aggression moves" carried out with South Korea and Japan, and said the US push to deploy "strategic assets" on the South was aimed at provoking another war.
Strategic assets can typically include aircraft carriers, long-range bomber aircraft or missile submarines. "Such insolent behavior of the US fans the anger and revenge of the Korean people," KCNA said.
South Korea to 'protect freedom and peace'
Marking the war anniversary in Seoul, Yoon pledged to do his utmost to protect freedom and peace.
"We will maintain strong security posture based on South Korea-US alliance and a strong military backed by science and technology," he wrote on Facebook.
Saturday's anniversary came amid concerns Pyongyang could conduct what would be its seventh nuclear test, which US and South Korean officials have said could take place "any time" now.
