Iran..

But to go back to Iran for a moment, an oil tanker hit a mine. It was following an Iran directed route, the U.S. military told it to follow their route instead and they led the tanker into a mine.

There is some speculation that the U.S. military intentionally led the tanker into a mine to escalate location tension, but there is zero evidence of this. What we do know now is the Iran route was safe, but the U.S. route was not, intentions are unknown.
