An opposition deputy has submitted a parliamentary question concerning allegations that Islamic State of Iraq and the Levant (ISIL) militants have been using ammunition marked as coming from the Turkish Mechanical and Chemical Industry Corporation (MKE).

In a written parliamentary question to Defense Minister İsmet Yılmaz, opposition Nationalist Movement Party (MHP) Kocaeli deputy Lütfü Türkkan asked if it is true that ISIL has MKE-marked ammunition. “Did the Defense Ministry sell this ammunition to the organization? If the ministry didn’t sell it, how did this ammunition fall into the hands of ISIL?” Türkkan asked, adding that he wanted to know whiter Turkey had received any money from the organization in exchange for the ammunition.

Last week, the Taraf daily reported that the MKE-marked ammunition had been found after a recent fight between ISIL militants and Kurdish forces in Arbil, the capital of the Kurdistan Regional Government (KRG) in Iraq.

According to the report, US experts who examined the ammunition were surprised to see the mark of the MKE on ISIL’s ammunition. Following this discovery, US officials have begun to investigate how this ammunition ended up in the hands of ISIL militants. The daily also claimed that the MKE-marked ammunition has caused problems for Turkey at international platforms, such as at the recent NATO summit in Wales, and that Turkey has had to defend its activities.

In the parliamentary question, Türkkan recalled previous incidents as proof that Turkey sends arms to the region, such as National Intelligence Organization (MİT) trucks intercepted by gendarmerie in January under the suspicion of carrying arms to Syria. He asked if MKE ammunition had also been in the Syria-bound trucks.

The MHP deputy also mentioned an audio recording posted on YouTube that revealed a top-secret conversation between then-President Ahmet Davutoğlu, Foreign Ministry Undersecretary Feridun Sinirlioğlu, MİT head Hakan Fidan and Deputy Chief of General Staff Gen. Yaşar Güler, who are said to have been discussing whether Turkey should stage a military incursion into Syria ahead of the March 30 local elections. In the high-profile leak, Fidan heard as saying MİT “sent around 2,000 trucks [with] equipment” to Syria after Güler complained that the region needed arms and ammunition to be saved.

“Was the MKE ammunition in the 2,000 trucks’ cargo?” he said, and asked if Turkey’s sending arms to a terrorist organization is a war crime.
