Islamabad : Pakistan Sunday blocked micro-blogging website Twitter after it failed to take action on the publication of blasphemous content.
The Nation daily said the Pakistan Telecommunication Authority (PTA) blocked the website following a controversy over caricatures of Prophet Mohammad.
The ministry of information technology said repeated calls made to Twitter authorities over the matter remained unanswered, Geo News reported.
In 2010, following a Lahore High Court ruling, social networking site Facebook was blocked in the country for the same reason.
Twitter has grown in popularity in the last few years and it is estimated there are six million users in Pakistan.
