US blames Iran for drone attack in Syria

U.S. officials announced Monday that Iran was behind last week's drone attack at a military base in Syria.

According to the Associated Press, Iran encouraged the attack, while covertly providing resources to facilitate it. 

Officials say that as many as five Iranian drones were involved in the strike, laden with explosives and shrapnel.

When asked about the strike, Pentagon press secretary John Kirby called it a "complex, coordinated and deliberate attack."

"​​The protection and security of our troops overseas remains a paramount concern," Kirby said during a press briefing. "If there is to be a response, it will be at a time and a place and a manner of our choosing, and we certainly won’t get ahead of those kinds of decisions."

Iranian media outlets say the attack was coordinated by pro-Syrian allies. 

No injuries or fatalities were reported as a result of the attack.
