Pakistani authorities have contacted social media website Facebook for help in investigating the posting of "blasphemous content" on the platform by Pakistanis, according to a statement.
The move comes after Nawaz Sharif, Pakistan's prime minister, ordered a ban on all online content deemed to be "blasphemous" on Tuesday.
Blasphemy is an extremely sensitive issue in Pakistan. Insulting the Prophet Muhammad carries a judicial death sentence and, increasingly commonly, the threat of extrajudicial murder by right-wing vigilantes.
"There have been positive developments in the matter of the Pakistani government's contact with Facebook's management regarding the blocking of blasphemous content," an interior ministry spokesperson said in a statement on Thursday.
Facebook would be sending a representative to visit Pakistan with regard to the matter, the statement said, and the government has appointed an official to liaise directly with the social networking website regarding the censoring of certain content.
