Turkey’s US and European allies continue to maintain a near silence over the country’s steady descent into a human rights nightmare, even as respected global watchdogs chronicle the abuses taking place there on an almost daily basis. Whether it is silencing the media, torture during detention or mass violence against civilians in the mainly Kurdish southeast, according to rights defenders, Turkey is beginning to resemble the Middle East dictatorships that it was once touted as a model for them to follow.

Now, a new and critical voice has joined the chorus of rebukes: the United Nations High Commissioner for Human Rights. In an unusually harsh statement, the Geneva-based high commissioner, Zeid Ra’ad al-Hussein, lambasted Turkey over a list of shocking crimes the security forces are widely alleged to have committed during a 78-day round-the-clock curfew between December 2015 and March that was slapped on Cizre, a Kurdish majority town on the Iraqi border. A crucible of Kurdish rebellion since the 19th century, Cizre was the scene of some of the worst violence in the latest outbreak of fighting between the security forces and the outlawed Kurdistan Workers Party (PKK) that erupted in August 2015.

The Jordanian diplomat said he had received reports of “unarmed civilians, including women and children, being deliberately shot by snipers, or by gunfire from tanks and other military vehicles.” In videotaped comments posted on Twitter, Hussein elaborated on the “massive” and “highly disproportionate destruction of property” by the Turkish security forces.

“Most disturbing of all,” he said, “are the reports quoting witnesses and relatives in Cizre, which suggest that more than 100 people were burned to death as they sheltered in three different basements that had been surrounded by the security forces.”
