Facebook, Twitter and YouTube are reportedly being blocked in Turkey during what appears to be an attempted military coup.
Military factions in Turkey tried to take control of the country Friday night, according to media reports, as some social media sites went dark. Many residents appear to have gotten around the blocks, posting messages and videos, likely using VPNs or other anonymizing services. Many people are streaming live video of the upheaval to Facebook.
Turkish President Recep Tayyip Erdoğan used his iPhone's FaceTime app to broadcast messages and urge the public to resist the coup attempt, according to The New York Times.
A YouTube spokesperson said the company is aware of reports the video site is down in Turkey, but added that "our systems seem to be functioning normally."
