(VOA NATO leaders are meeting Thursday in Brussels to discuss their short-term and long-term response to Russia’s month-old invasion of Ukraine, and they are due to hear a direct appeal from Ukrainian President Volodymyr Zelenskyy for more help.

Ahead of the meeting, Zelenskyy used a video message, delivered in English, to ask NATO members for “effective and unrestricted” support, including weapons for Ukrainian forces.

Zelenskyy also appealed to people around the world to hold public protests against the Russian invasion.

“Come with Ukrainian symbols to support Ukraine, to support freedom, to support life,” Zelenskyy said. “Come to your squares, to your streets, make yourselves visible and heard.”

In addition to the NATO talks, U.S. President Joe Biden is meeting Thursday with G-7 leaders and the European Council. National security adviser Jake Sullivan said the overall goal is to hear “the resolve and unity that we’ve seen for the past month will endure for as long as it takes.”

Sullivan said that includes countries following through on commitments to supply military equipment to Ukraine, to enforce existing sanctions against Russia and to look for ways to augment both along with humanitarian aid for those affected by the fighting.

Biden is due to announce a new round of sanctions targeting Russian political figures, oligarchs and other entities.

NATO Secretary-General Jens Stoltenberg told reporters Wednesday the alliance is expected to announce the deployment of four new battle groups to the alliance’s eastern flank as part of its additional defensive measures since Russia’s invasion of Ukraine.

The combat-ready units are set to deploy to Bulgaria, Hungary, Romania and Slovakia, according to Stoltenberg, bringing the total number of NATO battle groups on its eastern flank to eight. The other NATO battle groups have been fully operational in the Baltic States and Poland since 2017.

“I expect leaders will agree to strengthen NATO’s posture in all domains, with major increases of forces in the eastern part of the alliance on land, in the air and at sea,” Stoltenberg said, adding that Russia’s aggression is creating a “new normal” for NATO security.

The alliance chief said NATO leaders are also set to announce an agreement to address nuclear, chemical and other threats from Russia.

“I expect allies will agree to provide additional support, including cybersecurity assistance as well as equipment to help Ukraine protect against chemical, biological, radiological and nuclear threats,” he said.

Biden administration officials have previously sounded the alarm that Moscow could use chemical weapons in Ukraine and blame the Ukrainians for their use as part of a false flag operation to justify the Russian invasion. The president has previously warned that Russia would pay a severe price if it launched a chemical weapons attack but hasn’t specified what that response would involve.

Secretary of State Antony Blinken said Wednesday that Russian forces have committed war crimes in Ukraine and that the United States will work to hold Russia accountable.

“We’ve seen numerous credible reports of indiscriminate attacks and attacks deliberately targeting civilians, as well as other atrocities,” Blinken said, adding that many of the apartment buildings, schools, hospitals and other infrastructure hit “have been clearly identifiable as in-use by civilians.”

The assessment was based on a careful review of public and intelligence information gathered since Russia launched its invasion of Ukraine last month, according to the secretary.

Russia has repeatedly rejected accusations of war crimes.

A senior U.S. defense official told reporters Wednesday that Ukrainians have pushed Russian forces back to about 55 kilometers east and northeast of Kyiv, whereas a day earlier they were about 20 to 30 kilometers away.

Russian forces are still trying to encircle Chernihiv but are stalled between 8 and 10 kilometers from the city center, the official added.

Stoltenberg told reporters the Ukrainian military’s resilience is the result of the courage of the Ukrainian people and a military that is stronger than it was when Russia invaded and annexed Crimea eight years ago.

A NATO official who was speaking on the condition of anonymity to discuss intelligence told reporters Wednesday that between 7,000 and 15,000 Russian soldiers have been killed in Ukraine.

The official said Russian forces have achieved “almost none” of their strategic objectives, while noting “they are stalled” in the northern cities of Kyiv, Kharkiv and Chernihiv.

Russia is “achieving more results in the south, but the price is horrendous,” the official said.

On its English-language Telegram feed, Russia’s Ministry of Defense portrayed a vastly different war effort, praising Russian forces as they advanced on parts of southeastern Ukraine while Ukrainian forces fled, and claiming success in taking out Ukrainian fuel depots and positions with “high-precision long-range” weapons.

The United Nations says more than 3.6 million refugees have fled Ukraine since Russia launched its invasion one month ago. Another 6.5 million people have been displaced from their homes within the country.)
