Two car bombs were detonated in Reyhanli, Turkey, killing at least 43 people and wounding at least 140 others Saturday.

Turkish officials placed blame for the incident on a group with ties to Syria, according to the Associated Press. The car bombs went off 15 minutes apart. Deputy Prime Minister Besir Atalay indicated that while the bombers were based in Turkey, they were linked to Syria's intelligence service.

“We have to a great extent completed our work toward identifying the assailants,” Atalay said. “We have established that the organization and assailants have links to the pro-regime mukhabarat [intelligence] organization.”

Bulent Arinc, another deputy prime minister, said if it's proven that Syria was behind the bombings, his nation would “do whatever is necessary.” It's currently unclear whether military action is among any necessary options.

The American embassy in Ankara, Turkey, issued a statement condemning the “murderous attack.” The statement also indicated that the U.S. “stands with the people and government of Turkey to identify the perpetrators and bring them to justice.”
