Turkey's prime minister says "strong evidence" indicates two suicide bombers were responsible for twin explosions that killed at least 95 people and wounded hundreds more during a peace rally Saturday in the capital of Ankara.
Turkish Prime Minister Ahmet Davutoglu added there would be three days of mourning for the victims. It was believed to be the deadliest attack in Turkey in years.
No one has yet claimed responsibility for the explosions.
One of the explosions was captured on video as demonstrators gathered outside a train station in Ankara for the peace rally. Of the injured, 28 people were in critical condition, said Turkish Health Minister Mehmet Muezinoglu.
Turkey's government said it imposed a temporary news blackout in the wake of the explosions. A government spokesman said the blackout applies to gruesome or bloody images or ones that may "create a feeling of panic."
NSC Spokesperson Ned Price said in a statement the United States "condemns in the strongest terms today’s horrific terrorist attack."
"The fact that this attack occurred ahead of a planned rally for peace underscores the depravity of those behind it and serves as another reminder of the need to confront shared security challenges in the region," the statement said.
Price offered condolences to the injured and the families of the victims. Price said the U.S. "will continue to stand side-by-side with the Turkish Government and people as together we take on the scourge of terrorism."
