After repeated criticisms of Russian President Vladimir Putin, opposition leader Alexei Navalny, who was arrested this month, filed for suspension of detention as "unjust arrest", but the court rejected it.
Continuing from last week, protests calling for Mr. Navalny's release are scheduled in various parts of Russia on the 31st, and there are concerns that supporters and the administration will clash again.
Russian opposition leader Alexei Navalny was allegedly attacked by chemical weapons nerve agents last year and was arrested this month shortly after returning from Germany.
He was arrested for violating his obligation to regularly inform him of his whereabouts while being convicted of a suspended sentence in a past criminal case.
After that, while a local court decided to detain him for 30 days, Mr. Navalny filed a petition to suspend the detention as "unjust arrest", and a hearing was held on the 28th.
Mr. Navalny attended an online hearing from the detained facility and protested, "I have never met a lawyer since I was arrested," but the court dismissed the complaint.
On the 23rd, large-scale protests calling for release were carried out over Mr. Navalny, and human rights groups said that more than 4,000 participants were detained by security forces in 131 cities.
Since Navalny's supporters have called for protests on January 31, there are concerns that the supporters and the administration will clash again.
