North Korean troops start fighting alongside Russians, say US, Ukraine officials

North Korea troops have begun fighting alongside Russians, a U.S. State Department spokesman said during a briefing on Tuesday.

"Over 10,000 DPRK (North Korean) soldiers have been sent to eastern Russia, and most of them have moved to the far western Kursk Oblast, where they have begun engaging in combat operations with Russian forces," spokesperson Vedant Patel told reporters.

A day earlier, Ukrainian President Volodymyr Zelenskyy said Ukrainian troops were facing 50,000 troops, including 11,000 North Korean troops deployed by Russia to its Kursk region, although Moscow will neither confirm nor deny their involvement.

U.S. Defense Secretary Lloyd Austin spoke Tuesday with his Ukrainian counterpart Rustem Umerov “to discuss battlefield dynamics and provide an update on U.S. security assistance” for the Eastern European country, according to Pentagon press secretary Major General Pat Ryder.

Ryder said, "the secretary reaffirmed President [Joe] Biden's commitment to surge security assistance to Ukraine."

The Pentagon also clarified the amount of money that remains available for Ukraine's military assistance. There is about $7.1 billion left in the Presidential Drawdown Authority, which includes $4.3 billion approved by Congress in April, plus $2.8 billion that became available after recalculations.

Additionally, there is about $2.2 billion available under the Ukraine Security Assistance Initiative program. Ryder again underscored that the U.S. would rush aid to Ukraine and use all available funds.

Ryder said the two defense leaders also talked about the implications of the thousands of North Korean troops now assessed to be mostly in western Kursk Oblast.

Airstrike kills mother, children

A Russia airstrike on Ukrainian President Zelenskyy’s hometown killed a mother and her three children and left 14 people wounded, officials said Tuesday.

Interior Minister Igor Klymenko said rescue and recovery operations were complete after the residential building in Kryvyi Rig was hit a day earlier.

The office of the prosecutor general said a 32-year-old woman and children who were 10 years, 2 years and 2 months old were killed.

In Russia’s Belgorod region, a Ukrainian drone attack started a fire at an oil depot, regional governor Vyacheslav Gladkov posted on the Telegram messaging app.

He said a tank caught fire and 10 fire crews responded in the Starkooskolsky District near the Ukrainian border.

The Russian defense ministry also said 13 Ukrainian drones were destroyed overnight, all in regions bordering Ukraine.

Ukraine’s air force said it shot down 46 Russian drones overnight.

In addition, Ukrainian’s military was “holding back a fairly large grouping of Russian troops – 50,000 of the occupier’s army personnel,” in the Kursk region, Zelenskyy said in his address to the nation Monday.

“Our forces' strikes on Russian arsenals have reduced the amount of artillery used by the occupier, and this is noticeable at the front. That is why we need decisions from our partners – America, Britain, Germany – on long-range capabilities,” Zelenskyy said. “This is vital. The further our missiles and drones can hit, the less real combat capability Russia will have.”

North Korea defense pact

The forces in Kursk include 11,000 North Korean troops deployed by Russia to Kursk, Zelenskyy has said, although Moscow will neither confirm nor deny their involvement.

State media in North Korea reported that country ratified a defense agreement with Russia on Tuesday, formalizing months of deepening security ties.

The deal "was ratified as a decree" of leader Kim Jong Un, the Korean Central News Agency (KCNA) said Tuesday.

The notice comes after Russian lawmakers voted unanimously last week to ratify the deal, which President Vladimir Putin later signed.

"The treaty will take effect from the day when both sides exchanged the ratification instruments," KCNA said.

Putin and Kim signed the strategic pact in June, during Putin’s visit to North Korea.
