Who are the Russian dissidents still serving time after Alexei Navalny died behind bars?

TALLINN, Estonia (AP) — Russian President Vladimir Putin is expected to secure his fifth term in power this month on the heels of opposition leader Alexei Navalny’s death in prison, which devastated Kremlin critics and spurred concerns about the safety of other imprisoned dissidents.

Putin has gone from tolerating dissent to suppressing anyone who dared challenge him during his 24-year rule. Over the past decade, his government has restricted freedom of speech and assembly, targeted people considered threats to the Kremlin, and restricted access to many independent news outlets.
