South Korea’s president has met a visiting Ukraine delegation and called for a joint response to the threat posed by North Korea’s recent dispatch of more than 10,000 soldiers to support Russia’s war against Ukraine.

President Yoon Suk Yeol held closed-door talks with a Ukrainian delegation in Seoul, Wednesday, and discussed support measures for the country amid its war with Russia, according to the presidential office.

Researchers at SI Analytics, a South Korean satellite imagery firm that uses AI technology to scour images, also confirmed the new construction at the February 11 plant, saying in a report on Monday that some of the construction near the loading area would likely be used to conceal the future operations of the factory from satellites.
