The legislature in Russia's second-largest city has passed a bill outlawing promotion of homosexuality to minors, a move decried by LGBT rights activists. 

The bill, passed Wednesday, Feb. 29 by the city, calls for fines of up to 500,000 rubles ($16,500) for spreading homosexual propaganda and up to 1 million rubles ($33,000) for material promoting pedophilia. 

The measure gives only vague guidelines on what would be considered propaganda. 

Igor Kochetkov, a prominent gay activist in the city, said the bill “contains elements of neo-Nazi ideology (and) follows the logic of any totalitarian regime.” 

The mayor has 10 days to decide whether to sign the measure into law. 

Same-sex activity among adults was decriminalized in post-Soviet Russia, but anti-gay sentiments remain strong.
