More than 1,600 people have been arrested amid mass protests across Russia over the arrest of opposition leader Alexei Navalny.

The 44-year-old, a thorn in the side of the Kremlin for years, was arrested on January 17 when he returned to Moscow from Germany, where he had spent five months recovering from a nerve-agent poisoning.
