Moscow police on Saturday detained two women attempting to hold an unsanctioned Gay Pride demonstration.

According to the AP, the demonstration took place across from the Moscow mayor's office.

Reuters reported that other activists drove by the mayor's office waving rainbow flags. Some of the protesters were dressed as Eurovision Song Contest winner and Austrian drag queen Conchita Wurst.

Moscow authorities have denied gay groups' applications for permission to hold rallies for nine consecutive years.

Former Moscow Mayor Yury Luzhkov aggressively shut down any unauthorized pro-gay demonstrations, which he called “Satanic acts” and “one of the factors in the spread of HIV infection.”

Last year, Russian lawmakers approved a law banning the promotion of “gay propaganda” to minors, which targets any public demonstration of support for LGBT rights. Russian President Vladimir Putin has defended the law as necessary to protect children.
