Several vessels transiting through the Strait of Hormuz have been attacked in recent days, underscoring the “very real” risks that remain for shipowners in the Persian Gulf whether or not a peace accord is signed, Chevron Corp. Chief Executive Officer Mike Wirth said.

“There still has been kinetic activity this week, some of which has been reported in the media — some of which has not,” Wirth said on Bloomberg TV on Friday. “We see risks very real still in that environment.”
