The Kremlin on Friday blamed a surge in COVID-19 cases on reluctance to have vaccinations and "nihilism" after a record 9,056 new infections in Moscow, mostly with the new Delta variant, fanned fears of a third wave.

Moscow Mayor Sergei Sobyanin extended restrictions he had imposed this month, which include a ban on events with more than 1,000 people, an 11 p.m. closing time for restaurants, and the closure of fan zones set up for the European soccer championship.

He had said earlier this week that the situation in the capital, home to 13 million people, was deteriorating rapidly.
