Russia blocks access to websites of Alexei Navalny and close allies

Action comes as Kremlin increases pressure on opponents and critics ahead of parliamentary elections

Russian authorities have restricted access to Alexei Navalny's website and those of dozens of his close allies, the imprisoned opposition leader's team has said.

The action came as the government increased pressure on opposition supporters, independent journalists and human rights activists ahead of the country's parliamentary election. The September vote is widely seen as an important part of Vladimir Putin's efforts to cement his rule before a 2024 presidential election.
