Lahore: The Pakistan government is blocking all anti-Islam material on the Internet, particularly on social networking websites including Facebook.

The Pakistan Telecommunication Authority (PTA) and Information Technology Ministry is blocking all websites that carry blasphemous material, Deputy Attorney General Naveed Inayat Malik told the Lahore High Court on Monday.

After Malik gave this assurance on behalf of the federal government, Chief Justice Ijaz Chaudhry disposed of petitions seeking a ban on Facebook and several other websites.

An inter-ministerial committee is screening websites to block access to blasphemous and anti-Islamic material, he said.

The Chief Justice told Malik that the inter-ministerial committee should keep the High Court's Additional Registrar informed of its operations and the steps taken against objectionable websites.

He observed that if the PTA and the Information Technology Ministry fail to fulfill their responsibilities, the petitioners would be free to approach the court again.

Responding to an application seeking the registration of a First Information Report against the owners of Facebook for allegedly committing blasphemy, the Chief Justice said police should investigate the matter and dispose of the matter as per the law of the land.

The petitions were filed by lawyer Muhammad Azhar Siddique and the Islamic Lawyers Forum.
