Pakistan on Thursday blocked access to YouTube - a day after it shut down the social networking site Facebook - in response to an online group calling on people to draw the Prophet Mohammed.
The Pakistan Telecommunication Authority ordered operators to shut down YouTube "in view of growing sacrilegious contents on it," officials said in a statement.
PTA said Thursday it reached its decision after all "possible avenues were used within its jurisdiction, including using regular channels available on the Facebook and YouTube to launch protest, to avoid appearances of derogatory material available on their websites."
Facebook was blocked a day before "Everybody Draw Mohammed Day," which was scheduled by several Facebook groups dedicated to the idea.
The largest of the groupsÂ was unavailable for several hours Wednesday and Thursday. Facebook said "a small technical issue prevented some users from accessing this page and others for a very short period of time," and that Facebook had corrected the problem as quickly as possible once they became aware of it.
"While it may be considered objectionable to some, the Facebook Pages and Groups in question do not violate our policies," Facebook global communications director Debbie Frost said.
The page was online as of Thursday morning Eastern time.
