“We will continue our fight against the pawns that carry out such attacks, which know no moral or humanitarian bounds, and the forces behind them with more determination every day,” Erdogan said in a statement.
Military forces traveling on board buses came under attack during Wednesday evening rush hour after a car laden with explosives went off killing 28 people.
Reports say images recorded at the scene of the blast showed the charred wreckage of at least two buses and a car plus a large plume of smoke above central Ankara.
Turkish authorities said they had no information of who carried out the attack, but they suspect the Kurdistan Workers’ Party (PKK) to be behind the Ankara bombing. Other security sources from Turkey’s mainly Kurdish southeast point at the Islamic State militants.
World leaders and NATO members have joined the Turkish President in condemning the bombing as a “terrible” and “vicious” attack. They reaffirmed their solidarity with Turkey in combatting “the shared threat of terrorism,” as put by the State Department.
