Turkish Prime Minister Ahmet Davutoglu says two explosions at a Kurdish party rally which killed two people just days before key parliamentary elections were acts of "sabotage and provocation."

Turkey holds parliamentary elections on Sunday in which the Kurdish votes will be crucial in determining whether the ruling party gets the supermajority it seeks.

Officials have not confirmed whether the blasts at the People's Democratic Party rally Friday was caused by bombs. But the private Dogan news agency, without citing sources, said Saturday that one of the explosions was caused by explosives placed in a gas cylinder.

Davutoglu did not point to anyone as responsible for the incident.

A prosecutor said Friday that about 100 people were injured, most of them from the panic and a stampede following the blasts.
