Russian opposition leader and prominent Putin critic Alexei Navalny has been sentenced to 30 days in prison for breaking public protest laws, reports Al Jazeera.

Why it matters: Navalny was convicted in January but sentenced more than six months later, a delay he claims was part of the Russian government's efforts to stop him from leading nationwide protests over pension reform on Sept. 9. Navalny has been jailed several times for organizing protests against Putin and for other charges he says are bogus. He was barred from running for president in January.
