Egypt has banned 21 websites, including the main website of Qatar-based Al Jazeera television and Huffington Post Arabic, for “supporting terrorism”, state news agency MENA and security sources said on Wednesday.

While local media didn’t list all the affected URLs, Reuters sources said the government blocked them, because it believes they’re affiliated with Qatar — Al Jazeera is based in Doha, the country’s capital — or the Muslim Brotherhood.

The blocked websites include Mada Masr, Al Jazeera, Al Sharq, Masr Al Arabia, Arabic 21, Huffington Post Arabic, Horria post, Klmty, Rassd, elshaab among many others.

Egypt once shut down the internet in 2011 and blocked VoIP services like Skype and Viber in 2015.
