Investigation: Ankara bombers brought explosives from Kobani

As the investigation into last Sunday's Ankara bombing continues, investigators have discovered more evidence concerning how the deadly attack – in which 35 civilians were killed and over a hundred people were wounded – was organized.

The investigation process unveiled that after deciding to perpetrate the attack, 300 kilograms of explosives, including TNT, RDX and ammonium nitrate covered with beeswax, were brought by Vahit Kılıç and M.V.D. from Kobani, Syria, which is controlled by the PKK-linked Democratic Union Party (PYD), and buried in an area in the southeastern province of Şanlıurfa, across the border from Kobani. According to sources from the investigation, V.C., whose brother is the mayor of Şanlıurfa's Viranşehir district, which is run by the PKK-linked Peoples' Democratic Party's (HDP) regional affiliate, the Democratic Regions Party (DBP), helped Kılıç to cross the border.

Evidence indicates that Kılıç met with Seher Çağla Demir, who is suspected of having crossed the border from Syria and arranged for the car that was used in the attack in Şanlıurfa. He came to Ankara on Feb. 26 with Demir after meeting with PKK militants in the southeastern province of Diyarbakır. They then stayed with Özgür Ünsal, the second suicide bomber, at his mother's house until moving to another house in the city.

Nearing the day of the attack, terrorists in Şanlıurfa loaded the buried explosives into luggage, and M.V.D. traveled to Ankara by bus on March 11 and was met by Kılıç and Demir. Security camera footage from Ankara's intercity bus terminal, AŞTİ, indicates that the three sat in a cafe for some time.

A MOBESE camera indicates that Kılıç and Demir then loaded up the car in Ankara's suburban district of Çamlıdere. According to a report in Milliyet daily that was published on March 17, there is footage of terrorists in the bomb-laden car just hours before the deadly attack, and three terrorists, Demir, Ünsal and Kılıç, are seen in a white BMW with the license plate number "34 HGH 44."

Investigators suspect that Kılıç left Ankara before the attack in another rented car, which was found abandoned in Şanlıurfa this week. The company that rented the vehicle called the police and confirmed that the car belongs to the company. His whereabouts are still unknown, and he is suspected of having escaped to Syria.
