(CNN)An explosion hit military vehicles at an intersection in the Turkish capital of Ankara on Wednesday evening, officials said, in what the military called a terror attack.

Twenty-eight people were killed and 61 others were injured in the blast, according to Deputy Prime Minister Numan Kurtulmus.
Powerful explosion in Ankara

The explosion hit three military vehicles and a private vehicle in central Ankara, near Turkish Parliament buildings, Turkey's semiofficial Anadolu news agency reported, citing Ankara Gov. Mehmet Kiliclar. The vehicles were stopped at a traffic light at the time, the military said.

Authorities believe a bomb-laden vehicle caused the explosion, Kiliclar said, according to Anadolu.

Video aired on CNN Turk showed large flames reaching toward the night sky from an area on the ground. Lights from numerous emergency vehicles flashed nearby.

No group has claimed responsibility.

"Our determination to respond in kind against such attacks against our unity and future from outside and inside is even more strengthened through such attacks," Turkish President Recep Tayyip Erdogan said in a statement. "Turkey will not hesitate to use its right to self-defence anytime, anywhere, and in all situations."

Soner Cagaptay, a senior fellow at the Washington Institute for Near East Policy think tank, said that if it was a bomb attack, suspects could include ISIS or the PKK, the Kurdish militant separatists that Turkey considers a terrorist group.

"There's definitely many reasons why Turkish reaction is going to be fierce" if this was an attack, he said.
