President Zelensky: 11,000 North Korean troops already ”stationed” in Kursk

Ukrainian President Volodymyr Zelenskyy claimed on the 4th (local time) that "11,000 North Korean troops are already stationed in Kursk, Russia."
Kursk, in southwestern Russia, is an area where Ukrainian forces crossed the border and occupied part of the territory on August 6, and are currently engaged in fighting with Russian forces.
According to Reuters, President Zelensky said in his speech on the same day that he had received a report from his intelligence team on the movements of the North Korean military.
The number of North Korean troops stationed in Kursk that President Zelensky mentioned this time far exceeded previous figures.
On the 31st of last month, U.S. authorities revealed that approximately 8,000 North Korean troops were gathering in Kursk and preparing to fight against the Ukrainian military.
In addition, the Ukrainian Defense Intelligence Service (DIU) announced on the 2nd of this month that “North Korean troops have been deployed on the Ukrainian border,” totaling more than 7,000 as of the end of last month.
"We are seeing an increase in North Korean military forces, but we are not seeing an increase in the reaction of our friendly countries," Zelensky said. "We are seeing a more proactive response from the West."
I regret that he is not there," he said.
