Two bombs targeting a crowd of peace marchers Saturday in the Turkish capital have killed at least 86 people and injured 186 others, Turkey's health minister said, according to the Associated Press.
The explosions occurred minutes apart at a morning peace rally in Ankara organized by civil society groups, reports said.
It was unclear if the bombings were suicide attacks or involved explosives detonated remotely, and there was no immediate claim of responsibility.
Turkish Prime Minister Ahmet Davutoglu called an emergency cabinet meeting Saturday, local media said.
Turkey has been hit by a fresh wave of violence as government troops battle ethnic Kurdish separatists waging a guerrilla campaign for more autonomy.
