The Wall Street Journal reported that Iran was behind the attack. Tehran had warned earlier Thursday that ships must use its designated corridors through the strait, rather than the more southerly route backed by the U.S.
The White House did not immediately respond to a request for comment on the attack or IMO’s decision to suspend the evacuation. The U.S. benchmark crude price, which has been steadily falling since the agreement, jumped more than 2 percent Thursday afternoon.
Nearly 50 vessels transited the waterway Wednesday, the highest single day since the conflict began, according to maritime intelligence firm Windward. It reported, however, that at least five vessels traversing the southern corridor had turned back as of Thursday morning after Iran issued the new threat.
Dominguez had announced the IMO campaign Tuesday, aiming to end “months of hardship and distress” for more than 11,000 seafarers who have been stuck in the strait since the war began. It said the effort was backed by the U.S., Iran, Oman and other Gulf countries.
