MOSCOW (AP) — Some Russian activists have sued Madonna for millions of dollars, claiming they were offended by her support for gay rights during a recent concert in St. Petersburg.

Anti-gay sentiment is strong in Russia. In St. Petersburg, a law passed in February makes it illegal to promote homosexuality to minors, and the author of that law has pointed to the presence of children as young as 12 at Madonna's concert on Aug. 9.

Russian news agencies quote Alexander Pochuyev, a lawyer representing the nine activists, as saying the suit was filed Friday against Madonna, the organizer of her concert, and the hall where it was held, asking for damages totaling 333 million rubles, or nearly $10.5 million.
