An Ankara court blocked access to 40 Twitter, 2 Facebook accounts along with 4 websites over their postings on alleged government fraud in the Apr 16 referendum, on Tuesday.

A constitutional amendment that gives more power to President Recep Tayyip Erdoğan was approved by a slight majority on April 16, although debates over alleged voting irregularities have yet to ease. The opposition and international observers say as many as 2.5 million voters could have been “manipulated,” effectively changing the result. Hundreds of “No” voters have taken to the streets since then.

The court accused the implicated social media accounts of “praising terrorism, inciting violence, promoting crime, threatening national security.”
