At least 20 people have been killed and over 50 others injured in explosions early Saturday outside the main train station in the Turkish capital Ankara, according to media reports. The attack took place during a peace rally aimed to call for an end to the renewed violence between Kurdish rebels and Turkish security forces.

Turkish authorities said the blasts were a "terrorist attack" and they are investigating claims that suicide bombers were responsible. Prime Minister Ahmet Davutoglu has reportedly called an emergency security meeting to discuss the attack, which comes at a time of growing security concerns in Turkey.

Following the blasts, Davutoglu's office reportedly said he was suspending his election campaign programs for the next three days. President Recep Tayyip Erdogan also cut short his program in Istanbul to return to Ankara, the Associated Press (AP) reported.

"There was a massacre in the middle of Ankara," Lami Ozgen, head of the Confederation of Public Sector Trade Unions, or KESK, said, according to the AP. "Two bombs exploded in very short intervals."

The attack also comes ahead of a parliamentary election scheduled for Nov. 1.
