Singer Madonna has been summonsed to appear in a Russian court for violating an anti-gay law in St. Petersburg.

According to RT, activists suing Madonna have obtained her New York City address and sent her a summons to appear in court on October 25.

The suit was filed by nine anti-gay activists who claim “moral damages” over Madonna's support for gay rights during a Thursday, August 9 concert in St. Petersburg.

The petitioners are demanding reparations from Madonna, the organizer of her concert and the concert hall where she played. According to Ria Novosti, petitioners claim “moral damages” stemming from “the open promotion of homosexuality” and are asking for $10.5 million in compensation.

Madonna openly defied city authorities who had threatened to fine the pop star.

“We want to fight for the right to be free,” she told the audience, most of whom were wearing pink wristbands distributed at the door. Madonna urged them to “show your love and appreciation to the gay community.”

“She insulted believers' feelings, she promoted homosexuality when there were children at the concert and this is forbidden in St. Petersburg,” Darya Dedova of the pro-Kremlin group Trade Union of Russia Citizens, which backs the suit, is quoted as saying. “We, the residents of the cultural capital, suffered a colossal moral damage.”

An October 11 hearing was postponed because plaintiffs could not notify the pop star.

Working against plaintiffs is the fact that tickets cautioned against anyone under 18 from attending the show. (A video report is embedded on this page. Visit our video library for more videos.)
