Russian women should avoid sex with non-white foreign men during the World Cup because they could become single mothers to mixed-race children, a senior lawmaker in Moscow said on Wednesday.
Even when Russian women marry foreigners the relationships often end badly, said Tamara Pletnyova, head of the parliament's committee for families, women and children. Women are often stranded abroad or in Russia but unable to get their children back, she said.
She spoke in response to a question from a radio station about the so-called "Children of the Olympics" after the Moscow Games in 1980, a time when contraception was not widely available in the country.
The term was used during the Soviet era to describe mixed-race children conceived at international events after relationships between Russian women and men from Africa, Latin America or Asia. Many of the children faced discrimination.
"These [mixed-race] kids suffer and have suffered since Soviet times," Pletnyova told Govorit Moskva radio station.
"It's one thing if they're of the same race but quite another if they're of a different race. I'm not a nationalist, but nevertheless I know that children suffer. They are abandoned, and that's it, they stay here with mum," she said.

Pletnyova said she that she would like Russian citizens to get married "out of love regardless of their ethnicity."
Another lawmaker said foreign fans could bring viruses to the World Cup and infect Russians.
In comments to Govorit Moskva radio station, Alexander Sherin also said Russians should be careful in their interactions with foreigners as they might try to circulate banned substances at the tournament.
Thousands of football fans from 31 countries are travelling to the World Cup in Russia that kicks off on Thursday with an opening ceremony in the capital followed by a match between the host team and Saudi Arabia.
FIFA and the Russia 2018 organising committee did not immediately respond to a request for comment about Pletnyova's remarks.
Pletnyova is a lawmaker for the KPRF Communist Party, a nominally opposition party that backs President Vladimir Putin's Kremlin on most key issues.
Russians make up the majority ethnicity in the country, but there are dozens of minority groups, as well as a large labour migrant force predominantly from Central Asia and the South Caucasus.
