A plaque to mark the home of slain Russian politician Boris Nemtsov in the central Russian city of Yaroslavl has been removed.
The plaque was discovered missing on April 15, although it is not known when it was removed.
In February 2016, Nemtsov's supporters installed the plaque to mark the first anniversary of his assassination outside the Kremlin in Moscow. Nemtsov was serving as a deputy in the Yarsoslavl city council when he was killed.
In March, acting Yaroslavl Mayor Aleksei Malyutin said the plaque, which described Nemtsov as a "patriot," might be removed because the authorities had rejected the application to install it.
Authorities in Moscow have rejected all requests to name a city landmark after Nemtsov, who served as deputy prime minister under former President Boris Yeltsin and who was an unrelenting critic of President Vladimir Putin.
