Thousands of people are marching in Moscow to remember Russian opposition leader, Boris Nemtsov, who was shot dead outside the Kremlin in 2015. Nemtsov, a reformer, democrat and a deputy prime minister under former President Boris Yeltsin, was a fierce critic of President Vladimir Putin.
Five Chechen men went on trial for the killing in October.
They deny the charges and Nemtsov’s relatives fear whoever ordered the murder will never be found.
Separately on Sunday, anti-Kremlin activist IldarDadin, the first person jailed under new laws targeting protests, was released from a Siberian prison. The Supreme Court had overturned his conviction on Wednesday. He says he was tortured by staff at the prison, an accusation officials deny.
numbering thousands rather than tens of thousands, are moving slowly towards a square in the city.
Our correspondent says the marchers have not been given permission to travel to the Moskvoretskybridge where Nemtsov was shot dead, but some will probably go anyway.
The bridge has already been lined with flowers of tribute.
The rally appears peaceful, although green ink was thrown into the face of Putin critic and former PM Mikhail Kasyanov as he marched on Sunday.
Rallies are also expected in St Petersburg and other cities.
