Tens of thousands of Jews who fled oppression in the former Soviet Union are returning to Russia to make the most of an economic boom, even though a new strain of anti-Semitism is emerging in their old homeland.

Around one million Jews fled during the Soviet era and the post-communist chaos. Those returning now from Israel, the United States and Europe hope to use their new skills and old knowledge to do business.

"Now there are services here, like in New York and Paris, but the lifestyle is more interesting than in either of them - it's easy to understand why thousands are coming back," said Yevgeny Satanovsky, president of the Russian Jewish Congress.
