Russia's anti-Kremlin opposition said it was planning a nationwide protest next weekend despite
police forcibly detaining over 1,000 people on Saturday for attending what they said was an illegal march in
Moscow to demand free elections.
Saturday's protest, conceived by opposition activists as a peaceful walk to protest against the exclusion of their candidates from a Moscow
election next month, was systematically and sometimes violently dispersed by police.
Russian investigators had initiated a criminal case against one man, accusing him of injuring a police officer, the TASS news agency reported.
