President Joe Biden has announced that the United States is closing its airspace to Russian planes, asserting that this along with other punitive measures would weaken Russia.

"Tonight, I am announcing that we will join our allies in closing off American air space to all Russian flights " further isolating Russia " and adding an additional squeeze " on their economy. The Ruble has lost 30 per cent of its value," Biden told lawmakers in his maiden State of the Union Address on Tuesday.
