Qatar-owned Al-Jazeera is suing the Egyptian government over its crackdown on the broadcaster's activists and journalists.

The network said in a statement posted online Wednesday that it had "no other option" but taking legal action through the International Centre for Settlement of Investment Disputes (ICSID) in Washington DC. It said the move came months after Cairo declined to respond to the network's complaints.

The network says Egyptian authorities have caused it to incur losses of $150 billion.

Al-Jazeera was widely seen as a mouthpiece for Islamist President Mohammed Morsi's Muslim Brotherhood group. After his 2013 overthrow, Egypt revoked Al-Jazeera's press credentials, raided its offices and arrested several reporters.
