WASHINGTON—President Biden has for the first time authorized Ukrainian forces to use Western-made long-range weapons to strike inside Russia, allowing Kyiv to better defend itself against Russia, according to U.

President Joe Biden has for the first time authorized the use of U.S.-supplied long-range missiles by Ukraine to strike inside Russia.

The Biden administration will allow Kyiv “limited” use of the ATACMS long-range missile system to strike enemy positions in Kursk, a significant reversal of U.S. policy.

North Korea may deploy as many as 100,000 troops to aid Russia’s war on Ukraine if the alliance between Pyongyang and Moscow continues to deepen, according to people familiar with assessments made by some Group of 20 nations.

President Joe Biden authorized Ukraine to use U.S.-supplied long-range missiles inside Russia for the first time Sunday, according to multiple reports—an escalation of U.S. involvement in the conflict in response to North Korean troops being sent to aid Russia.

North Korea could deploy up to 100,000 soldiers to help the Kremlin with its war in Ukraine — a figure that could boost Russian President Vladimir Putin’s fighting force in Ukraine by up to 20%, according to a new report.

Soldiers from North Korea are reportedly fighting alongside Russia in Ukraine, and initial conflicts have emerged. A recording featuring a Russian Orthodox priest has surfaced online. In it, he claims that the Koreans "brought a plague to the country" and advises soldiers not to heed the "devilish words" of the godless.
