That’s all from me, Tom Ambrose, and the Ukraine live blog for today. Thanks for following along.

Here is the latest on the news that more than 1,000 North Korean soldiers have been killed or wounded since they were sent to fight alongside Russian troops in Ukraine, according to South Korean military officials.

Kremlin foreign policy adviser Yuri Ushakov said on Monday that he thought it likely that North Korean soldiers would take part in next year’s Moscow’s Red Square parade to commemorate the Soviet victory over Nazi Germany in the second world war.

Ukraine says North Korean soldiers have fought on Russia’s side against Ukrainian troops trying to hold territory in Russia’s Kursk region. Moscow has neither confirmed nor denied the presence of North Korean troops on its soil.

Russian president Vladimir Putin and North Korean leader Kim Jong-un signed a “Comprehensive Strategic Partnership Treaty” during Putin’s visit to Pyongyang in June.

The pact includes a mutual defence pact for immediate military assistance if either faces armed aggression.
