SEOUL, June 18 (UPI) -- 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.

The announcement came on Tuesday as Russia's Security Council Secretary Sergei Shoigu visited North Korean leader Kim Jong Un in Pyongyang for the second time this month.

Kim "has decided to send 1,000 sappers to Russia to clear mines on Russian territory, as well as 5,000 military construction workers to restore infrastructure destroyed by the occupiers," Shoigu said, according to Russian state media TASS.

Russian news agency RIA Novosti also reported on the visit, saying Shoigu came to Pyongyang on special instructions from Russian President Vladimir Putin.
