Thousands of opposition supporters have participated in a rare unsanctioned march in the Russian capital, Moscow.
Sunday's "stroll" was called for by several prominent writers, including acclaimed novelist Boris Akunin.
An estimated 7,000 people attended the two-kilometer walk which ended in a plaza where opposition activists have been camped out.
The gathering is one of several protests to take place in the capital since the election of President Vladimir Putin to a third term.
Police have detained hundreds of people in the past week.
