The blaze, which officials said was likely caused by an electrical fault, tore through the wooden interior of a dormitory in the southern region of Adana last evening.
Riot police stopped around 150 protesters from different organisations including left-wing groups and women's rights activists from demonstrating outside the education ministry in Ankara over allegations that negligence led to the blaze.
Police later detained an unknown number of demonstrators as they tried to run away, an AFP photographer said.
Last month, the Ankara region banned all public gatherings and demonstrations until the end of November after receiving information about potential terror attacks.

But Deputy Prime Minister Veysi Kaynak rejected this, saying that according to initial findings the door had been unlocked.
In Adana, police authorities today detained eight people, including the manager of the dormitory in the Aladag district, as part of the investigation into accusations of "causing death by negligence".
