The total number of cases of coronavirus infections in Russia crossed the 3 million mark for the first time on Saturday after officials recorded 29,258 new cases in the preceding 24 hours and 567 deaths.

This brought the total number of cases of coronavirus in Russia since the start of the pandemic to 3,021,964, according to official data.

Previously, Russian authorities have ordered those arriving from the U.K. to quarantine for two weeks. Earlier this week, Russia suspended direct flights from the U.K. after a variant of the coronavirus that is 70% more transmissible has spread across London and parts of England. The order from the Rospotrebnadzor sanitary safety agency posted Friday on the portal of official information obliges all those traveling from the U.K. to remain in isolation for 14 days after their arrival in Russia. The measure is effective starting Saturday. Dozens of countries have barred flights from the U.K. or announced travel restrictions.

Russia was the first country in the world to approve a vaccine against the virus last month. The move elicited criticism from experts worldwide as the shots have only been tested on a few dozen people and further studies are needed to establish the vaccine’s safety and effectiveness.
