The United States and its European allies announced sanctions against Russia after Moscow decided to recognize the independence of the Donetsk and Lugansk people's republics.
On Monday, Russian President Vladimir Putin signed decrees recognizing the independence of the Donetsk and Lugansk people's republics. Under the new treaties, Moscow will ensure the security of the two Russian-speaking republics.
The decision followed a deterioration of the situation on the line of contact between Ukraine and the breakaway republics amid interference by the West. Russia has repeatedly denied having any intention of invading Ukraine.
