June 4 (Reuters) - Russian police on Sunday arrested more than 100 people who had taken to the streets to mark the 47th birthday of Alexei Navalny, Russia's most prominent opposition leader, a protest monitoring group said.
OVD-Info said in a statement that 109 people had been detained in 23 cities as of 10:42 p.m. Moscow time (1942 GMT).
Footage from Moscow and St Petersburg, Russia's two largest cities, showed police arresting individual demonstrators.
Another man, who held up a sign in English that read "Free Navalny", was also arrested in Moscow.
In St Petersburg, a woman accompanied by a child told reporters that "I'm against the war, that's why they detained me with my underage kid".
