An all-female rock group was detained after holding an unsanctioned concert on Red Square at which they performed a song with the chorus "Rebellion in Russia."

Photographs posted on the group's blog page showed its members dressed in brightly colored dresses and stockings Friday, standing on the outside wall of Lobnoye Mesto, a centuries-old platform across from the Kremlin on which tsars' decrees were once read.

The group, called Pussy Riot, said they performed a song that began with the lyric, "A column that has risen up in rebellion is moving toward the Kremlin."

The group said on Twitter that several of its singers were in police custody. They were later freed.
