Pakistan is not the only country to have blocked access to YouTube.
In January, a court in Turkey blocked the site because some video clips allegedly insulted the country's founding father, Mustafa Kemal Ataturk. It is illegal to insult Ataturk in Turkey.
Last spring the Thai government banned the site for about four months because of clips seen as offensive to Thailand's revered monarch, King Bhumibol Adulyadej.
Moroccans last year were unable to access YouTube after users posted videos critical of Morocco's treatment of the people of Western Sahara, a territory Morocco took control of in 1975.
