The Associated Press reports: Thousands are marching in a pro-invasion rally in downtown Moscow one day after Russia’s parliament gave President Vladimir Putin a green light to use military force in Ukraine.

At least 10,000 people bearing Russian flags marched freely through Moscow on Sunday, while dozens of people demonstrating on Red Square against an invasion of Ukraine were quickly detained by Russian riot police.

The Associated Press witnessed over 50 detentions and spotted at least five police vans, which carry between 15 and 20 protesters, driving away from the square.
