Russian President Vladimir Putin defended Russia's anti-gay law Sunday, linking homosexuality with pedophilia and stating Russia needs to "cleanse" itself of gays if it wants to increase its birthrate.

Putin's comments in an interview broadcast Sunday with Russian and foreign television stations displayed the wide gulf between Putin’s views on homosexuality and that of many in the West ahead of the Winter Olympic Games in Sochi that could be overshadowed by the debate.

A Russian law passed last year banning "propaganda of nontraditional sexual relations" among minors has caused an international outcry and led to calls to boycott the games, due to take place in February.

Putin refused to answer a question from the BBC on whether he believes that people are born gay or become gay. The Russian law, however, suggests information about homosexuality can influence a child's sexual orientation.

The legislation has been blamed for contributing to growing animosity toward gays in Russian society, with rights activists reporting a rise in harassment and abuse.

International concern about how gay people will be treated in Sochi have been met with assurances from Russian officials and Olympics organizers that there will be no discrimination in Sochi, and Putin reiterated that stance Sunday.

"There are no fears for people with this nontraditional orientation who plan to come to Sochi as guests or participants," Putin said in the TV interview.

He added that the law was aimed at banning propaganda of homosexuality and pedophilia, suggesting that gays are more likely to abuse children.

Defending his views on homosexuality, Putin noted with pride that Russia saw more births than deaths last year for the first time in two decades. Population growth is vital for Russia's development and "anything that gets in the way of that we should clean up," he said, using a word usually reserved for military operations.

Putin accused the United States of double standards in its criticism of Russia, pointing to laws that remain on the books in some U.S. states classifying gay sex as a crime. The U.S. Supreme Court, however, ruled in 2003 that such laws were unconstitutional.

Homosexuality was a crime in the Soviet Union, which collapsed in 1991. It was decriminalized in Russia in 1993.
