Qatar’s state-run broadcaster Al Jazeera is taking legal action against Egypt’s military-backed government for shutting down its offices and arresting its reporters.

“Al-Jazeera has instructed lawyers to take all steps necessary worldwide to ensure that its journalists can operate freely in the country without fear of arbitrary arrest, assault, jamming or other forms of harassment and intimidation,” the network said in a statement on Thursday.

In a bid to “ensure that freedom of expression and freedom of the press do not die in Egypt,” the network also appealed to the United Nations, the statement added.

Earlier this month, the media network said that its team of experts recognized locations east and west of the Egyptian capital Cairo where the jamming appeared to be originating.

The jamming of the Arab broadcaster was traced to sites near Egyptian military bases including the military intelligence headquarters and the army’s public-relations department.

Al Jazeera’s offices in Cairo have been shut down since July 3, when they were attacked by Egyptian security forces hours after former President Mohamed Morsi was ousted.

Egypt has since been the scene of increasing violence.

The army-appointed government has launched a bloody crackdown on Morsi supporters and arrested more than 2,000 Muslim Brotherhood members.

About 1,000 people were killed in a week of clashes between Morsi supporters and security forces after police dispersed their protest camps in a fatal crackdown on August 14.

The massacre sparked international condemnation and prompted world bodies to call for an independent investigation into the violence.
