The People's Council, an anti-gay group in Russia, claims that Vesyoly Molochnik milk being sold in St. Petersburg violates the city's ban on homosexual propaganda.

The milk carton contains a rainbow, "a world-renowned symbol of the gay movement," according to Anatoly Artukh of the People's Council. "That immediately put me on alert," he told Australia's ABC News.

St. Petersburg passed the controversial "homosexual propaganda" law in March. The law makes "propagandizing sodomy, lesbianism, bisexualism, and transgenderism among minors" a criminal act. Similar laws exist other Russian cities.

"Our life has been quite funny in the last year or so with the introduction of the homosexual propaganda law in November," Polina Savchenko, the director of advocacy group Coming Out, told ABC News. "You know, it could be funny. It's so ridiculous, and so middle-aged, that it could be funny, but unfortunately it's not funny because we know that they're serious."

State prosecutors are investigating whether the milk company, which is owned by Pepsi Co, violated the law.
