Van national education director Kiyasettin Kirekin said that the incident took place on Saturday night in Edremit district; the three-story public school was extensively damaged.
PKK supporters came to the school’s garden, damaged security cameras, broke first-floor windows, then threw Molotov cocktails inside.
Firefighters came to the scene quickly and controlled the fire.
“The building has become unusable and the cost of damage is around 200,000 Turkish liras ($70,000),” Kirekin said.
He condemned the attack, saying that the Turkish government will repair the building, making it ready for the next semester.
The PKK – listed as a terrorist organization by Turkey, the U.S. and EU – resumed its 30-year armed campaign against Turkey in July last year.
Since then, more than 350 Turkish security personnel have been martyred and thousands of terrorists killed.
