Ukraine reportedly recaptures two towns as US says Russia ramping up Donbas attacks: LIVE UPDATES

Alina Beskrovna, a refugee who fled Ukraine and now lives in Poland, said she witnessed Ukrainian melt snow to have drinkable water.

She also said Ukrainians were forced to cook on open fires despite giving away their position to potential Russian forces, "because if you don’t, you will have nothing to eat.”

“A lot of people are just, I think, starving to death in their apartments right now with no help," she said. "It’s a mass murder that’s happening at the hands of the Russians.”

Ukraine President Volodymyr Zelenskyy warned during his nightly address that Russian forces were attempting to regroup ahead of a potential next assault on Kyiv.

“We still have to fight, we have to endure,” Zelenskyy said. “We can’t express our emotions now. We can’t raise expectations, simply so that we don’t burn out.”

The nightly address came as U.S. intelligence officials believe the Ukrainian military has retaken the Irpin suburb and town of Trostyanets from Russian occupation.

President Biden's perceived regime change comments are pushing Vladimir Putin further away from the negotiation table and could prompt the Russian dictator to show a greater display of force if he feels trapped "into a corner" by the West, a former KGB agent warned Monday.

"Every time our president makes a personal attack on Vladimir Putin, I cringe because Putin is paranoid," Jack Barsky said during an interview on "The Story." "In his mind now, it makes no sense to negotiate whatsoever because come peace, then he will be hunted down."

Russia has not given up on its goal to surround and capture the Ukrainian capital of Kyiv.

Russia continued to deploy additional troops with the goal of encircling and eventually capturing Kyiv, according to a Sunday report from the Institute for Study of War.

Russian forces are continuing the push on Kyiv “despite statements by officials from the Ministry of Defense and the General Staff of the Russian Federation regarding changes in plans and priorities," signalling Moscow has not given up on taking Ukraine's capital city.

The report notes that Russia is also continuing its effort to take other major Ukrainian cities, saying there has been no move of combat power away from what have been major Russian military objectives.

International media blasted President Biden for his unscripted remark Saturday when he declared Russian President Vladimir Putin "cannot remain in power," concluding it was a gaffe that hurt more than helped the effort to support Ukraine amid the ongoing Russian invasion.

Biden called the invasion a "strategic failure" and pledged continued U.S. aide for Ukrainians in his address. But it was his off-the-cuff comment about Putin that made headlines.

"For God’s sake, this man cannot remain in power," Biden said to conclude his speech in front of the Royal Castle in Warsaw, Poland.

Russia’s bloody invasion of Ukraine has forced the staff to transform Kyiv’s largest hospital, Clinical Hospital #8, into a battleground medical facility, according to a recent Wall Street Journal report.

Dermatologists and cardiologists now assist with triaging wounded patients arriving from artillery and rocket barrages as the hospital sits within 10 miles of the battleground, the paper noted. 

The staff are numb to the air raid sirens because they are so frequent to take seriously anymore, and don’t wear face masks because of the constant background noise of fighting as they try to talk to communicate, per the Journal.

"Of course we are not what we used to be, but neither is the rest of the country," said Dr. Igor Khomenko, the hospital director.

Russian oligarch Roman Abramovich and at least two senior Ukrainian peacekeepers suffered symptoms from a suspected poisoning attack but have since recovered, according to a report published Monday. 

Following a meeting in the Ukrainian capital of Kyiv earlier this month, Abramovich and the two senior members of the Ukrainian peacekeeping team, including Crimean Tatar lawmaker Rustem Umerov and a second unnamed individual, began experiencing symptoms that included red eyes, constant and painful tearing, and peeling skin on their faces and hands, The Wall Street Journal reported. 

Citing unnamed sources familiar with the incident, the newspaper said it’s not clear who was responsible for the alleged attack, but the victims pointed to hardliners in Moscow trying to sabotage talks to end the war. Abramovich, Umerov and the third officials have since improved in condition and their lives are not in danger following the suspected poisoning, the sources said. 

The sources added that Western experts said it was difficult to determine whether the symptoms were caused by a chemical or biological agent or by some sort of electromagnetic-radiation attack.

President Biden on Monday released his $5.8 trillion budget proposal for 2023, which he said calls for "one of the largest investments in our national security in history," including funding to ensure the U.S. military "remains the best-prepared, best-trained, best-equipped military in the world," amid Russia’s multi-front war on Ukraine.

The White House released the president’s FY 2023 budget Monday morning, which "sends a clear message that we value fiscal responsibility, safety and security at home and around the world," the president said.

"I’m calling for one of the largest investments in our national security in history, with the funds needed to ensure that our military remains the best-prepared, best-trained, best-equipped military in the world," the president said.

Biden said he is also calling for "continued investment to forcefully respond" to Russian President Vladimir Putin’s "aggression against Ukraine, with U.S. support for Ukraine’s economic, humanitarian and security needs."

Pentagon Press Secretary John Kirby announced Monday that the U.S. is sending six Navy EA-18 Growler aircraft to Spangdahlem Airbase in Germany "to bolster readiness, enhance NATO's collective defense posture and further increase air integration capabilities with our allied and partner nations."

"These growlers, as those of you who are familiar with the platform know, are equipped for a variety of missions," Kirby said. "But they do specialize in flying electronic warfare missions, using a suite of jamming sensors to confuse enemy radars, greatly aiding in the ability to conduct suppression of enemy air defense operations."

About 240 Navy personnel will accompany the aircraft from Naval Air Station Whidbey Island in Washington state.
