Access to Twitter and YouTube have been blocked in Turkey.
The move come less than one week after Istanbul prosecutor Mehmet Selim Kiraz died when security forces stormed an office where the extreme leftist Revolutionary People’s Liberation Party-Front (DHKP-C) had taken him hostage.
Several Turkish newspapers said the blocks came after the group issued a picture of Kiraz with a gun to his head.
“A request has been made to both Twitter and YouTube for the removal of the images and posts but they have not accepted it and no response has been given. That’s why this decision has been taken through a court in Istanbul,” a senior Turkish official told Reuters.
Kiraz, 46, had been leading an investigation into the death last March of Berkin Elvan, 15, who died nine months after falling into a coma after being hit by a police teargas canister during anti-government protests in 2013.
The DHKP-C said on its website that the hostage-taking was in revenge for Elvan, whose death a year ago prompted renewed protests in parts of Istanbul.
Activists have accused Turkish authorities of covering up the circumstances of the 15-year-old’s death.
