What is the Biblical basis against inter-faith marriages? Setting aside marriages of couples from two different Christian denominations, what passages in the New Testament prohibit a Christian from marrying a non-Christian?

I believe that the Old Testament prohibits Jews from marrying non-Jews, but I am interested in answers relating to Christians specifically.
2 Corinthians 6:14-15 is often understood to prohibit the marriage of Christians with non-Christians:


  Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever?
