ISLAMABAD- YouTube will remain blocked in Pakistan, a government official today said as experts failed to find a way to filter content deemed offensive and blasphemous.

The website has been blocked in the country since September 2012 over its hosting a movie that sparked furious protests around the world. The Supreme Court ruled at the time that the site should be banned until a way was found to block all blasphemous content.

“The matter was reviewed several times but the situation effectively remains the same,” the minister for information technology and telecommunication Anusha Rehman told the Senate.

“The government does not want to take any chance and wants to make sure that after the unblocking YouTube, no offensive content remains viewable in Pakistan,” a senior government official said.

“So far no tool or solution has been found which can totally block offensive content, that is why YouTube remains blocked and it will remain so indefinitely,” the official said.

In November 2011, the telecommunications authority tried to ban nearly 1,700 “obscene” words from text messages.

Free speech campaigners have long complained of creeping censorship in the name of protecting religion or preventing obscenity, and have described the ban on YouTube as a violation of civil rights.
