Here is the link to the full story.
Twitter just announced that its mobile Web site is now available in Arabic and Farsi.
A Twitter spokesperson credited a team of volunteers:
Several weeks ago, we added translation support for right-to-left languages in the Twitter Translation Center, specifically for mobile.twitter.com. Since then, our awesome community of translators has been working hard to translate the mobile website. They completed the work for Arabic and Farsi quickly, and today we made them available to mobile.twitter.com users. We will continue to ship additional languages as they are ready.
