Mr Kirby added that the incident did not have any impact on the ship’s operations.
Mr Kirby continued: “When you have another armed force — in this case, the Iranian navy — that flies like this, you definitely run the risk of some sort of escalation and a miscalculation on either side here, and that’s not helpful.
“This one ended peacefully, but it doesn’t mean it was safe and professional.
“It absolutely wasn’t.”
The press sec added: “It’s dangerous because it could lead to miscalculations.”
