The suicide attack carried out at the U.S. Embassy in Ankara was “clearly an act of terror,” White House Press Secretary Jay Carney said Friday.

“A suicide bombing in the perimeter of an embassy is by definition an act of terror, a terrorist attack,” Carney told reporters at Friday's daily briefing.

He said that the United States “strongly condemns” the incident but cautioned that “we do not know at this point who is responsible or the motivations behind the attack.”

A Turkish guard was killed and three others wounded in the blast, which took place Friday afternoon inside a security checkpoint of the embassy, according to the Associated Press.

The question of how quickly the White House moves to label attacks on U.S. embassies “acts of terror” came up during the 2012 campaign, when GOP nominee Mitt Romney accused President Obama of taking “14 days before he called the attack in Benghazi an act of terror.”

In the days after the attack, Obama had indeed deemed it an act of terror. But administration officials had held off on labeling it as such, and in an interview two weeks later, Obama himself held back in an interview on ABC’s “The View.”
