Twitter’s service was blocked by Pakistan’s government Saturday, the company said in a tweet from its policy account .

“We are aware of reports that the Pakistani government has taken action to block Twitter service, as well as other social media services, and that users are having difficulty using Twitter in Pakistan. We are monitoring the situation and hope service will be fully restored soon,” Twitter’s statement reads.

Business Insider has reached out to Facebook for confirmation.It’s not clear why Pakistan is blocking social media sites, but the Associated Press reportedSaturday that the government sent in troops to address an Islamist sit-in in Islamabad.
