Moscow-based Russia Today was hacked and its website was defaced Saturday, the news station reported on Twitter.

"RT website has been hacked, we are working to resolve the problem," the official Twitter account wrote.

Hacker(s) defaced the website, in some places replacing "Russia" or "Russians" with "Nazi" or "Nazis." It was not yet clear who was responsible. The changes to the RT website remained in place for nearly 30 minutes before the station reported everything was back to normal.
