Pakistan has blocked access to the popular video sharing website YouTube.
No official reason has been given for the move, but the BBC reports one internet service provider saying it was aimed at containing "blasphemous" material.
On Wednesday a Pakistani court ordered access to be barred to social networking site Facebook in a row over a competition involving caricatures of the Prophet Mohamed.
Users who wanted to enter were asked to draw caricatures of the Prophet Mohamed. Islamic law prohibits the depiction of any prophet.
Latest reports say certain Wikipedia pages are also being blocked.
