First burning down the door of the offices, the aggressors then set the place to fire and run away.
Timely intervention of the fire squad avoided any harm to others living in the building.
Kadir Zeybek, chair of the union's Antalya branch protested the attack with a press conference.
Addressing to PM Tayyip Erdoğan, Zeybek urged the government to bring the aggressors to justice in due time.
"Provocative speeches made to gain political profits lead to the formation of cliques in the society and as a result attacks towards those who promote democracy and rights increase. This last incident is not unrelated to the increasing nationalist-reactionary wave in the country".
About hundred people attended the meeting, protesting the attack chanting "Unite against fascism" and "we won't give into oppression".(HÜ/TK/EÜ)
