Muslims from around the U.K. traveled to London to take part in the demonstration, the Telegraph reported, and there are plans to hold another protest against the anti-Islam movie trailer in Hyde Park in the coming weeks. The upcoming Hyde Park protest is expected to draw nearly one million protesters, the U.K. newspaper added.
Google has refused to pull the controversial online video from YouTube because it contends that the clip does not violate its guidelines on banning violent or pornographic content.
Masoud Alam, an organizer of the protest in London, told the Telegraph that the video "is not freedom of expression, there is a limit for that." Alam added that the protests would continue until the clip was removed.
The search giant has blocked access to the video in Egypt, Libya and India because it is believed to have spurred violent protests, according to Reuters. Brazil, Saudi Arabia and other countries have all urged Google to remove clips of the trailer from its site.
A YouTube spokesman told the Telegraph that the video will remain on the site.
"We work hard to create a community everyone can enjoy and which also enables people to express different opinions," the YouTube spokesman told the Telegraph. "This can be a challenge because what's OK in one country can be offensive elsewhere. This video — which is widely available on the Web — is clearly within our guidelines and so will stay on YouTube."
