Egypt's top administrative court ruled on Saturday that regulators must block the video file-sharing site YouTube for one month over a video that denigrates the Prophet Mohammad, a lawyer who filed the case told Reuters.
A lower administrative court had ordered that the Ministry of Communications and Information Technology block YouTube, owned by Google, in 2013 over the video, but the case was appealed and its ruling stayed during the appeal process.
The ministry at the time said it would be impossible to enforce the ruling without also disrupting Google's Internet search engine, incurring potentially huge costs and job losses in the Arab world's most populous country.
The Ministry of Communications and Information Technology was not immediately available for comment. YouTube appeared to be working in Egypt on Saturday as of 1250 GMT.
The film "Innocence of Muslims", a low-budget 13-minute video, was billed as a film trailer and made in California with private funding. It provoked a wave of anti-American unrest in Egypt and other Muslim countries when it appeared in 2012.
Mohamed Hamid Salem, a lawyer who filed the case in 2013, said the ruling also orders that all links that broadcast the film be blocked.
The ruling is considered final and cannot be appealed.
