Maybe a response to the Israeli ship that was hit with a mine this past weekend?

I don't think this was a response to that mine explosion, but rather just a new event in a series of on going attacks to Iranian ships. That mine explosion however was likely a response from Iran.
"A third maritime security source told Reuters that three other Iranian ships had been damaged in recent weeks by unknown causes when sailing through the Red Sea."
"Meanwhile the Wall Street Journal reported that Israel has targeted at least a dozen vessels bound for Syria and mostly carrying Iranian oil"
