Russia-Ukraine updates: Putin says 'certain positive movements' in negotiations

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.
