MOSCOW (AP) — Rating agency Fitch has downgraded the outlook for Russia's credit rating fearing an economic fall-out from the Crimean crisis.

Fitch says it's revised the outlook for Russia's debt to reflect the potential impact of sanctions on Russia's economy. On Thursday, S&P warned of a potential downgrade, too.

The Russian stock market has lost more 10 percent this month, wiping out billions in market capitalization.

And Russia's stock market has taken a pounding today.
