Secretary of State John KerryJohn KerryFormer Obama officials say Netanyahu turned down secret peace deal: AP How dealmaker Trump can resolve the Israeli-Palestinian conflict John Kerry to teach at Yale on global issues MORE said on Monday that he was outraged by the footage of U.S. sailors being apprehended at gunpoint by the Iranian military last week.
"I was very angry. I was very frustrated and angry that that was released. I raised it immediately with the Iranians," he said during an interview on CNN.
"There's no excuse for it," he added later.
Last week, 10 U.S. Navy sailors were taken into custody by the Iranian coast guard after they, as Kerry put it, "regrettably, inadvertently went into Iranian waters" due to a mechanical problem. They were released the next day.
Iran released footage that showed the captured sailors on their knees with guns pointed at them.
The secretary of State also argued that the improved relationship between Iran and the United States helped resolve the issue quickly.
"The challenge is that, three or four years ago you mentioned, we wouldn't have known who to call. We would have probably had to call the Swiss or maybe we would have called the British. There would have been no direct communication," he said.
