Ukrainian Foreign Minister Dmytro Kuleba addressed the accounts of racism at the border by people of color attempting to flee, tweeting Tuesday, "Ukraine’s government spares no effort to solve the problem."

Germany Foreign Minister Annalena Baerbock also addressed the reports of racism and discrimination during a powerful speech at the U.N. Assembly on Tuesday.

"Every refugee must receive protection, no matter what their nationality, no matter what their religion, no matter of the color of their skin," Baerbock said.

Despite debate within the U.S. administration on whether Russia is suffering military setbacks in Ukraine, a senior U.S. official reiterated to ABC News that the invasion will be devastating for Ukraine.

"Putin is going to put Ukraine in a vice grip," the official said, adding that Putin has ratcheted up his determination to carry on.

The dominant analysis within the administration involves Putin acting out with incredible ferocity and intent, believing this is his destiny, the official said.

The massive Russian convoy heading toward Ukraine is just as mighty as it looks from satellite imagery, the official added.

Taking out just half a dozen of those tanks would seriously slow down the convoy, because the roads are surrounded by mud in many places, so it would be difficult for the tanks to maneuver around the crippled vehicles, the official said.

President Joe Biden is under pressure to act, but the U.S. military is wary about any proposals that would bring American troops into open conflict with Russia. The U.S. military is also adamant that about avoiding anything that would trigger conflict, the official said.

Oil giant ExxonMobil announced Tuesday it will be ending current and future investments in Russia.

Specifically, it will cease operations at its Sakhalin-1 venture, which the company operates on behalf Japanese, Indian and Russian companies.

"As operator of Sakhalin-1, we have an obligation to ensure the safety of people, protection of the environment and integrity of operations. Our role as operator goes beyond an equity investment," the company said in a statement.

ExxonMobil said its stoppage of investments in Sakhalin-1 will "need to be carefully managed and closely coordinated with the co-venturers."

The company added that it wouldn't invest in future developments in Russia.

Several Jewish groups condemned Russia for a missile attack that struck a Ukrainian Holocaust memorial.

The missiles struck the site of the Babyn Yar massacre where 33,000 Jewish men, women and children were killed in September 1941.

The Auschwitz Memorial and Museum in Poland tweeted, "It’s hard to expect the Russian army to respect the dead if it is not capable of respecting human lives."

The United States Holocaust Memorial Museum noted that Ukrainian President Volodymyr Zelenskyy visited the site last year to commemorate the 80th anniversary of the event.

"We stand with him and the Ukrainian people during these critical times," the museum said in a statement.

Israel’s Yad Vashem, the World Holocaust Remembrance Center, called on the international community to protect sites such as Babyn Yar as well as the innocent civilians caught in the crossfire.

"Rather than being subjected to blatant violence, sacred sites like Babi Yar must be protected," Yad Vashem said in a statement.

U.S. Secretary of State Antony Blinken crossed the border into Ukraine Saturday after meeting with Ukrainian Foreign Minister Dmytro Kuleba at the Korczowa Border Crossing Point.

"The entire world stand with Ukraine," Blinken said, and Kuleba added that he hopes Ukrainians will see this as a "clear manifestation that we have friends who literally stand by us."

Blinken said the sanctions imposed so far against Russia are "producing very, very concrete results" and that the pressure will "grow" until this "war of choice is brought to an end."

When asked directly about helping Kuleba with more firepower, Blinken said, "the support for Ukraine not only has been unprecedented, not only is going to continue, it's going to increase."

Kuleba said Ukraine "appreciates" sanctions that have been announced in the last week, but that more economic and political pressure and "necessary weapons," would "save many lives in Ukraine... many sufferings will be avoided."

Kuleba also said that they are “satisfied" with already arranged supplies of anti-tank weapons and ammunition, but that “it’s no secret” they still want fighter jets and air defense systems.

He also thanked the U.S. for sending stingers, and said they were used on Saturday.

"Just today we shot down three Russian attack aircrafts, which were bombing our cities with the use of stingers but we need -- so to say -- big air defense systems to ensure the safety of our skies. If we lose the skies, there will be much, much more blood on the ground,"Kuleba said.

In response to questions about NATO’s refusal to impose a no-fly zone over Ukraine, Kuleba said it’s a "sign of weakness," but stayed optimistic that they will change their minds.

"The time will come," he said.
