The Qatar-based Al-Jazeera TV network says it's taking legal action in international courts against the Egyptian government for closing its offices, jamming its signals and arresting its reporters.
The network is facing a government crackdown in Egypt, part of a campaign against media perceived as backing ousted President Mohammed Morsi and his Muslim Brotherhood.
An Egyptian court on Sept. 3 ordered Al-Jazeera's local affiliate to stop broadcasting, accusing it of hurting national security, "broadcasting lies" and vilifying the country's military.
At least two Al Jazeera reporters have been in detention in Egypt since August.
In a statement Thursday, Al-Jazeera says Egypt's new regime aims to silence it, and appealed to the United Nations to "ensure that freedom of expression and freedom of the press do not die in Egypt."
