Some people say Russia is in Eastern Europe. Isn't Russia in Asia?

I was always taught in school that Russia is part of Asia. Even Yahoo! Answers puts Russia in the Europe category instead of Asia Pacific. What's the truth?

Russia is in both Asia and Europe.

Asia

Russia is a huge country, and it extends from eastern Europe all the way to the eastern end of the Asian continent. Yahoo probably classifies it as European because the capital, Moscow, is in Europe, as are many major Russian cities. Also, Russia is often considered to have a European or Western culture, so it's not generally thought of as part of the "Far East."
