Islamabad, May 21: Pakistan seems to be on a 'blocking' spree as Twitter is the latest addition in the list of websites being blocked in the country.
Over the past couple of days, Pakistan Telecommunication Authority (PTA) decided to block popular social networking site, Facebook and video-sharing website Youtube over offensive content.
Twitter users from Pakistan were unable to log on the site on Friday, May 21 as the internet service providers had blocked access to the site.
Attempts to log on to the microblogging site were met with the message 'this site is restricted'.
The PTA began its crack down on the websites after the Lahore High Court directed it to block Facebook over a 'blasphemous' page dedicated for caricatures of Prophet Mohammad.
After Facebook, citing 'sacrilegious contents', PTA blocked Youtube.
In a statement issued on Thursday, May 20, the PTA said, "The government acted against both Facebook and YouTube after it failed to persuade the websites to remove the derogatory material."
