(NEW YORK) — Russian forces are continuing their attempted push through Ukraine from multiple directions, while Ukrainians, led by President Volodymr Zelenskyy, are putting up “stiff resistance,” according to U.S. officials.

The attack began Feb. 24 as Russian President Vladimir Putin announced a “special military operation.”

Russians moving from Belarus towards Ukraine’s capital, Kyiv, don’t appear to have advanced closer towards the city since coming within about 20 miles, although smaller advanced groups have been fighting gun battles with Ukrainian forces inside the capital since at least Friday.

Russia has been met by sanctions from the U.S., Canada and countries throughout Europe, targeting Russia’s economy and Putin himself.

Russians running out of food, gas: US official

The Russian forces charging toward Kyiv haven’t made progress in the last day as they face Ukrainian resistance and low food and gas supply, a senior U.S. defense official told reporters Tuesday.

However, it could be a deliberate pause, the official said. “Part of the stall could be … as a result of their own self-determined sort of pause in operations — that they are possibly regrouping, rethinking, reevaluating,” the official said.

The U.S. believes Russian forces “have committed now more than 80% of what was their pre-staged combat power,” the official added.

The official said some Russian soldiers weren’t told they were going into combat. The official said, “not all of them were apparently fully trained and prepared.”

The strong Ukrainian resistance has also hurt morale, according to the official.

Russia has now launched more than 400 missiles on Ukraine, the official said. The U.S. believes Russia has launchers that could be used for thermobaric weapons, but cannot confirm their use, the official said.

Russian forces are making the most progress in the south. Russians are attacking Kherson in south Ukraine, which “appears very much to be contested city at this point,” the official said.

Russians are also approaching Mariupol in southeastern Ukraine, and while they haven’t yet entered the city, “they are close enough now that they could attack Mariupol with long range fires,” the official said.

Two towns on the path to Mariupol are believed to be occupied by the Russians, according to the official.

The U.S. believes the Russians hope to move north out of Mariupol up to the heavily-contested city of Kharkiv. The official said they believe Russian forces are trying to encircle Kharkiv.

The U.S. official noted that they’ve seen “certain risk-averse behavior by the Russian military” over the last week.

“Take the amphibious assault, for instance. They put those troops ashore a good 70 kilometers away from Mariupol because they knew Mariupol was going to be defended and they could put them ashore in an uncontested environment. And they still haven’t reached Mariupol,” the official said.

“They are not necessarily willing to take high risks with their own aircraft and their own pilots,” the official said.

“And of course we’re seeing that on the ground — the fairly slow and steady progress that they have made, and you guys are seeing it for yourselves on the ground where … units are surrendering, sometimes without a fight.”

Russian missile hits Kyiv TV tower killing at least 5

The tower that provides the main signal to TV and radio in Kyiv has been struck by a Russian missile, leaving at least five dead, Ukrainian officials said.

Ukraine’s Foreign Minister Dmytro Kuleba tweeted that the tower “is situated on the territory of Babyn Yar. On September 29-30, 1941, Nazis killed over 33 thousand Jews here. 80 years later, Russian Nazis strike this same land to exterminate Ukrainians. Evil and barbaric.”

Ukraine’s President President Volodymr Zelenskyy tweeted, “What is the point of saying «never again» for 80 years, if the world stays silent when a bomb drops on the same site of Babyn Yar? At least 5 killed. History repeating.”

Western officials walk out during Lavrov remarks

Diplomats from Western countries were seen on video walking out in protest as Russian Foreign Minister Sergei Lavrov addressed the U.N. Human Rights Council and Conference on Disarmament.

The meeting was held Tuesday in Geneva and Lavrov gave his address via video.

The Human Rights Council has faced criticism for years for including human rights abusers, including Russia. In a prerecorded video to the council, Secretary of State Antony Blinken questioned whether Russia should be allowed to keep its seat.

“One can reasonably ask whether a U.N. member state that tries to take over another U.N. member state — while committing horrific human rights abuses and causing massive humanitarian suffering — should be allowed to remain on this council,” he said.

Blinken accused Russia of hitting civilian targets like schools, hospitals, residential buildings, critical infrastructure, and cars, buses, and ambulances — including the “monstrous rocket strikes” on an apartment complex in Kharkiv.

“Reports of Russia’s human rights abuses and violations of international humanitarian law mount by the hour,” he said.

“These are the human rights abuses this council was created to stop. If we cannot come together now, when will we come together?” he asked.

‘Growing number’ of unaccompanied and separated refugee children

Filippo Grandi, U.N. high commissioner for refugees, told the Security Council Monday there’s “a growing number of unaccompanied and separated children” in the unending lines of refugees fleeing Ukraine.

UNICEF said there are “anecdotal reports of heartbreaking stories of fathers — or families — arriving at the border with their children and relinquishing them to the border guards, then remaining in Ukraine.”

UNICEF said it doesn’t have numbers yet on unaccompanied or separated children.

About 660,000 refugees have fled Ukraine: UN

At least 660,000 people have fled Ukraine into neighboring countries in the six days since the Russian invasion began, the U.N. Refugees Agency said.

At the Polish border, UNHCR staff reported queues that were miles long.

“Those who crossed the border said that they had been waiting up to 60 hours,” the agency said on Tuesday. “Most arrivals are women and children from all parts of Ukraine. Temperatures are freezing and many have reported spending days on the road waiting to cross.”

Agency staff said people were waiting up to 20 hours to enter Romania. In Hungary, arrivals were “steady and waiting times vary.” The 37-mile trip between Odessa, Ukraine, and the border with Moldova was taking some refugees 24 hours, the agency said. And arrivals in Slovakia, where asylum laws were rapidly changed, were lower than elsewhere, agency staff said.

An unknown number of Ukrainian citizens have also been displaced within the country, Filippo Grandi, the agency’s commissioner, told the U.N. Security Council on Tuesday.

“The situation is moving so quickly, and the levels of risk are so high by now, that it is impossible for humanitarians to distribute systematically the aid, the help that Ukrainians desperately need,” he said.

The International Organisation for Migration said more than 470,000 people of various nationalities, “including a large number of overseas students and labour migrants,” are still in Ukraine.

Russian bombardment strikes central square in Kharkiv

Russia on Tuesday launched a major bombardment of Ukraine’s second-largest city, Kharkiv, hitting a central square and its civilian administration building.

Video from the scene shows a large projective hitting next to the regional state administration building on Kharkiv’s Freedom Square, causing a huge blast. Aftermath shot on phones from the scene and inside the building, show it shattered with debris strewn around.

Ukraine’s emergency services ministry said at least six people, including one child were injured. It was unclear if anyone was killed.

Kharkiv Mayor Oleg Sinegubov confirmed the strike, calling it a “war crime.”

Monday’s shelling followed a sustained bombardment of civilian areas yesterday and overnight in Kharkiv by Russian heavy artillery, including multiple rocket launchers and an alleged use of cluster munitions.

“What is happening in Kharkiv is a war crime!” Sinegubov wrote on Facebook. “The Russian enemy is shelling whole residential neighborhoods of Kharkiv, where there is no critical infrastructure, no Ukrainian armed forces positions, which the Russians could be targeting.”

Sinegubov accused Russia of conducting the attacks during the day, when civilians were on the street. He said the city’s emergency services are unable to keep up with the number of attacks and injured.

So far at least 11 are dead, with dozens injured, he said.

Russian forces in Kharkiv appear to have shifted tactics to employing heavy artillery indiscriminately against the city, in an apparent effort to bombard and terrorize it into submission.

Sinegubov claimed the Russians were changing tactics because their offensive capabilities on the ground were running out and so they had nothing left but to launch aerial bombardments.

Russian troops ‘operational’ near Ukrainian nuclear power plant, agency says

Ukraine said its nuclear power plants are still being operated “safely and securely,” the International Atomic Energy Agency wrote in an update late Monday.

However, IAEA Director General Rafael Mariano Grossi said he “remained gravely concerned about maintaining their safety and security during the current conflict.”

Ukraine’s foreign ministry told the IAEA on Monday that Russian troops are “operational” near a functioning nuclear power plant at Zaporizhzhia, but the troops haven’t entered it so far. Any fighting near nuclear facilities causes alarm, and Ukraine has four sites in total with 15 reactors.

“It is extremely important that the nuclear power plants are not put at risk in any way,” Grossi said in a statement. “An accident involving the nuclear facilities in Ukraine could have severe consequences for public health and the environment.”

The IAEA Board of Governors will hold a meeting Wednesday to discuss the “safety, security and safeguards implications of the situation in Ukraine.”
