MOSCOW—Russian authorities have restricted access to the website of imprisoned opposition leader Alexei Navalny and to dozens of sites run by his close allies, Navalny’s team said Monday.
The action came amid mounting government pressure on opposition supporters, independent journalists, and human rights activists in Russia ahead of the country’s parliamentary election. The September vote is widely seen as an important part of President Vladimir Putin’s efforts to cement his rule before a 2024 presidential election.
