The White House said on Wednesday it condemned the attack in Ankara that killed 28 people and wounded dozens near the armed forces' headquarters, parliament and other government buildings.

"We stand together with Turkey, a NATO ally, a strong partner, and a valued member of the counter-ISIL coalition in the face of this attack," said Ned Price, a spokesman for the White House National Security Council, using an acronym for the Islamic State group.

European Union (EU) foreign affairs chief Federica Mogherini said the EU extends condolences to the families of the victims killed in the latest car bomb attack in Turkish capital of Ankara.

She said in a statement that the EU is with Turkey and its people in these difficult times and stand by all those who suffer from the consequences of such violence, and of terrorism.

"The EU wishes a speedy recovery to those injured. Our fullest sympathy goes to the Turkish people and authorities," she said.
