A prominent opposition politician in Russia, former deputy Prime Minister Boris Nemtsov, has been sentenced to 15 days in prison after being arrested at a demonstration in Moscow on New Year's Eve.
He was convicted of disobeying police orders at the rally, which had not been authorised.
Mr Nemtsov has repeatedly criticised the government's record on human rights and democracy.
He says the court case was an attempt to silence him.
He was among 68 people arrested at the demonstration.
