The office of Egypt's top prosecutor issued a gag order on the investigation into the deadly attack this week in which Egyptian forces mistakenly killed eight Mexican tourists on a desert safari.
A statement from the prosecutor's office released on Wednesday evening says the ban applies to all media - print, radio, online, and television, both domestic and international.
It says the order will remain in effect until the investigation by the Egyptian authorities into the incident is concluded.
It also says the ban does not include statements from the top prosecutor's office.
