Biden closes U.S. sky for Russian aircraft

"The United States will close its airspace to Russian aircraft," Biden said. He has also promised to seize private planes, yachts and real estate from "Russian oligarchs" and "corrupt leaders" along with European allies.

Biden says the USA will join its European allies and further isolate Russia, which will intensify pressure on the Russian economy.

He also addressed "Russian oligarchs" and "corrupt leaders": "We are working with our European allies to find and seize your yachts, luxury apartments and private jets. We aim to expose your illegal purchases, and the US Department of Justice is setting up a task force to investigate the crimes of Russian oligarchs".
