Internet services in Turkey were slowed down following the release of a video by the Islamic State in Iraq and the Levant (ISIL) on Thursday showing two Turkish soldiers being burned to death.
According to the Turkey Blocks monitoring network, access to Twitter and YouTube was slowed down, affecting millions of Internet users in Turkey.
Turkey Blocks said the restrictions were first observed with fixed broadband operators Uydunet/Turksat and mobile providers Turkcell and Vodafone on Thursday.
ISIL allegedly burned alive two Turkish soldiers who it took hostage three weeks ago in the al-Bab region of northern Syria.
Photos and a video allegedly of the two soldiers were shared online on ISIL accounts late on Thursday.
The video came a day after 16 Turkish soldiers were killed and 31 injured in ISIL attacks in al-Bab.
