Russian opposition leaders arrested at anti-Putin rally
Russian police arrested prominent opposition leaders at a rally against President Vladimir Putin in Moscow.
Blogger and activist Alexei Navalny said on Twitter he had been detained at the rally in Lubyanka Square, which was banned by the authorities.
Fellow opposition leaders Ilya Yashin, Ksenia Sobchak and Left Front head Sergei Udaltsov were also arrested.
Police eventually broke up the rally, one of several nationwide that marked a year of protests against Mr Putin.
Mr Navalny later tweeted that he and the other opposition leaders had been released without charge.
In all, 40 people were arrested, police said.
Reports said police cleared the square by moving protesters towards a nearby metro station.
'Raving mad'
Mr Navalny, who has been one of the most vocal anti-Putin campaigners, tweeted: "This is the traditional and not very original tweet from the police detention van.
"It's raving mad. They snatched me out from the crowd."
