WASHINGTON — Some 8,000 North Korean soldiers are now in Russia near Ukraine's border and are preparing to help the Kremlin fight against Ukrainian troops in the coming days, the Biden administration said Thursday.
The new figure is a dramatic increase from a day earlier, when Defense Secretary Lloyd Austin would only say some of the troops had moved toward Ukraine's border in the Kursk region, where Moscow's forces have struggled to push back a Ukrainian incursion.
That also would mean most of the North Korean troops that the U.S. and its allies say have been sent to Russia are now on the border with Ukraine.
The U.S. has estimated a total of about 10,000 North Korean troops are in Russia. Seoul and its allies assessed that has increased to 11,000, while Ukraine has put the figure higher, at up to 12,000.
Of the 8,000 in Kursk, ''we've not yet seen these troops deploy into combat against Ukrainian forces but we would expect that to happen in the coming days,'' Secretary of State Antony Blinken said at a news conference in Washington with Austin and their South Korean counterparts.
Russia has been training North Korean soldiers in artillery, drones and ''basic infantry operations, including trench clearing, indicating that they fully intend to use these forces in front line operations,'' Blinken said.
North Korea's efforts to tighten its relationship with Russia has raised concerns around the world about how that may expand the war in Ukraine and what Russian military aid will be delivered in exchange.
It's become a key topic as U.S. and South Korean leaders met this week in Washington, fueling concerns that the presence of those soldiers will further destabilize the Asia-Pacific region and broaden Moscow's war on Ukraine.
