MOSCOW—More than 20,000 Russians took to the streets of Moscow on Sept. 29 to demand the release of protesters jailed over the summer in what opponents of the Kremlin say is a campaign to stifle dissent.
The protesters were arrested at rallies that flared in July when opposition politicians were barred from a local election. Allegations of police brutality and what many Muscovites saw as harsh jail sentences have sparked an unusual public outcry.
