Kurtulmus said that 28 people were killed and 61 others were injured in a car bomb attack that targetted a military convoy in the Turkish capital, speaking at a news conference late Wednesday.
Kurtulmuş said a bomb-laden car was detonated when the military buses stopped at a red light near the armed forces' headquarters.
The goverment's spokesman also said he suggests the casulties could have included both military and civilians because the explosion took place at a busy intersection less than 500 meters from parliament during the evening rush hour.
A seven-member prosecutor delegation, led by Ankara chief public prosecutor, launched a multi-lateral investigation into the attack, Kurtulmuş said. "The incident is being investigated with its all details. All findings are being rigorously searched."
The deputy PM also said ambulances and fire crews were sent to the scene just three minutes after the attack. “As many as 32 ambulances and emergency crews were involved in frantic efforts to treat injured."
Authorities in Ankara did not have any information about who or which outlawed organisation was behind the attack, he said.
“There is no statement about this but we will find out who was involved in the attack in a short time," Kurtulmuş noted, adding that
it was a treacherous attack which targetted the nation.
"We publicly curse those, who were involved in the attack, those, who used perpetrators as a tool, as well as all circles, who provided political, logistic, military support to such kind of assaults," he emphesized.
The spokesperson also emphatically rejected the claim which said a second explosion occurred in Ankara less than an hour after the first blast. “It was not an explosition.
Bomb-disposal experts made a controlled explosion of the package," he explained, citing the sound heard across many places in Ankara.
