Turkish authorities have shut down over 100 websites since July 25 for having alleged links to the outlawed Kurdistan Workers' Party (PKK), the media reported on Thursday.
The websites were said to have "links with the PKK" that demonstrated "support for terrorism", EFE reported.
In the last week of July, 96 websites - among them several media outlets - and 23 twitter accounts were closed by the head of telecommunications based on administrative decisions, then ratified by the courts.
News agencies Firat and Sendika.org were among the sites closed in the crackdown.
A group of Turkish and foreign intellectuals have since launched a campaign under the title "I do not accept censorship. I read Sendika.org" in support of the outlet.
Several journalism organisations have also protested against what they consider an act of censorship and an attack on the right to information.
