Turkey on Saturday blocked all access inside the country to the online encyclopedia Wikipedia, an Internet monitoring group said, but it was not clear why the ban had been imposed.
A block affecting all language editions of the website in Turkey was detected from 0500 GMT after an administrative order by the Turkish authorities, the Turkey Blocks monitoring group said in a statement.
Residents in Istanbul were Saturday morning unable to access any pages of Wikipedia without using a Virtual Private Network (VPN), AFP correspondents said.
