Bodies of victims are covered with flags and banners as police officers secure the area after an explosion in Ankara, Turkey, Saturday, Oct. 10, 2015.
The explosions occurred minutes apart near Ankara's train station ahead of a peace rally that aimed to call for an end to the renewed violence between Kurdish rebels and Turkish security forces, the Associated Press reports.
The Turkish government suspects that the twin blasts were a "terrorist" attack, an official said.
"We suspect that there is a terrorist connection," a government official told AFP, asking not to be named.
The rally was organized by the country's public sector workers' trade union.
