2017 block of Wikipedia in Turkey

Some countries have faulted Turkey for funding Islamist rebel groups in Syria, including al-Qaeda's affiliate in Syria, the al-Nusra Front. In October 2014, Vice President Joe Biden said that Turkey, Saudi Arabia and the UAE had “poured hundreds of millions of dollars and tens of thousands of tons of weapons into anyone who would fight against Al-Assad.”

The block occurred on April 30, 2017, two weeks after the Turkish constitutional referendum, which was held on April 16.

On 25 April, Turkey conducted several airstrikes on YPG, YPJ, and PKK facilities in both Syria and Iraq (Sinjar). 40 militants, including five Peshmerga soldiers, were killed at Iraq's Sinjar Mountains, and more than 20 YPG and YPJ fighters were killed on Syria's Mount Karacok. The Syrian Democratic Forces (SDF) threatened to withdraw from the ongoing operation to capture Raqqa if the United States didn't take measures to stop Turkey's airstrikes against the group. In response, the US began to patrol the border alongside SDF troops in order to force a ceasefire between its two allies.

Law No. 5651, known as the Internet Act (IA), was enacted on 4 May 2007. The purpose of this law was described by the now-defunct Presidency of Telecommunication and Communication as follows: "There are two reasons for the law to be brought. The first reason: to determine the liability and the responsibility of collective use providers, access providers, location providers, and content providers, which are the main actors of the Internet. The other reason is to determine the procedures and fundamentals related to the specific crimes committed over the Internet and fighting these through content, location and access providers." More recently, the law has been used to censor individuals, journalists and the media. At least 127,000 websites are estimated to have been blocked in Turkey, along with another 95,000 individual web pages.
