McDonald's announced Tuesday it is temporarily closing its restaurants and pausing operations in Russia, as a result of the invasion of Ukraine.

"The conflict in Ukraine and the humanitarian crisis in Europe has caused unspeakable suffering to innocent people. As a System, we join the world in condemning aggression and violence and praying for peace," the company's chief executive officer, Chris Kempczinski, said in a statement.

"We are experiencing disruptions to our supply chain along with other operational impacts. We will also closely monitor the humanitarian situation," Kempczinski said.

Poland announced Tuesday it is "ready" to "immediately" hand over all its MiG-29 fighter jets to a U.S. air base in Germany to boost Ukraine's fight against Russia.

Ukrainian President Volodymyr Zelenskyy has asked the West and NATO to supply Ukraine with fighter jets.

The Polish government said in a statement that will provide its Russian-made MiGs to the Rammstein Air Base "free of charge," placing them "at the disposal" of the U.S. government, and asked the United States to backfill them "with used aircrafts with corresponding operational capabilities."

"The Polish Government also requests other NATO Allies -- owners of MiG-29 jets -- to act in the same vein," the statement added.

A senior U.S. defense official told ABC News: "We have seen the Polish government’s announcement and have nothing to offer at this time."

A spokesperson for the U.S. Department of State told ABC News they are working with the Polish government and consulting with NATO allies on this.

"This is Poland's sovereign decision to make. We have in no way opposed Poland transferring planes to Ukraine. There are a number of challenging practical question," the spokesperson said. "In the meantime, we continue to surge security assistance for Ukraine and deliveries are ongoing."

A senior U.S. diplomat told ABC News that the U.S. was not "pre-consulted" on this news. U.S. Under Secretary of State for Political Affairs Victoria Nuland told the Senate Foreign Relations Committee that she found out about Poland's announcement while driving to Capitol Hill to testify.

"To my knowledge, it wasn't pre-consulted with us that they plan to give these planes to us, but as you know, we have been having consultations with them for a couple of days now about this request from the Ukrainians to receive this aircraft, and, were they to donate them, whether we would be able to help support backfill in their own security need," Nuland said.

Ukrainian intelligence claimed Tuesday that a Russian general was killed in fighting near the eastern city of Kharkiv. If confirmed, this would be the second general Russia has lost in Ukraine in a week, according to reports from Russian media last week.

Ukraine’s defense intelligence agency identified the general as Vitaly Gerasimov, chief of staff of the 41st Army.

Ukraine’s defense intelligence agency also published audio of an alleged intercepted phone call between two officers from Russia’s FSB intelligence agency discussing Gerasimov’s death.

Russia has not confirmed or denied the death.

The executive director of the open source group Bellingcat, Christo Grozev, said he had confirmed Gerasimov’s death with a Russian source. Grosev said Bellingcat had also identified the FSB officer in the alleged recording.

Last week, the 41st Army’s deputy commander, Major General Andrei Sukhovetsky, was confirmed by Russian media to have been killed.

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."
