Al Jazeera is reporting that its live Egypt service (Al Jazeera Misr) has been taken off the air, along with several other TV stations. According to the network's correspondents, it happened in the middle of a live broadcast.
Security forces apparently stormed the building, arrested the presenter, guests, and producers.
