Russia has announced a reward of 45,000 euros for information leading to the conviction of the killer of opposition figure Boris Nemtsov.
Supporters of the 55-year-old claim he died because of his fierce criticism of Vladimir Putin and for slamming the war in Ukraine as Russian “aggression”.
Investigators are examining security footage, some of which has been shown on Russian television.
Nemtsov is seen walking with his girlfriend, and another person is then seen running from the spot and getting into a car that stops nearby.
Russian authorities are promising a full investigation to hunt down the killers, but the opposition is voicing scepticism that the truth will ever be uncovered.
