North Korea will send 6,000 military workers and combat engineers to help rebuild Russia's Kursk region, Moscow's top security official said, in the latest show of growing ties between the two countries.

North Korea will send thousands to support reconstruction work in Russia's Kursk region. North Korea has already supplied combat troops and conventional weapons to back Russia's war against Ukraine.

Thousands of North Korean laborers are already toiling in Russia. A new contingent is headed to the region where North Korean troops fought Ukraine.
