Arabic version: ناقلات إيرانية تخترق الحصار البحري الأمريكي في خليج عمان

Three Iranian tankers loaded with crude oil have passed the US blockade line in the Gulf of Oman, according to ship-tracking data. Two of these vessels were broadcasting their locations as they crossed, while a third appeared to switch on its location tracker just past the line.

According to BBC News, despite President Donald Trump announcing the ‘immediate removal’ of the blockade of Iranian ports, US naval forces later confirmed it would remain in effect until the deal with Iran was signed. This agreement is expected to take place in Switzerland on Friday.

The tankers, identified as Diona, Hero II, and Sonia I, are owned by the National Iranian Tanker Company, which has been sanctioned by the US Treasury. These vessels are carrying a combined total of 3.8 million barrels of crude oil. If they make it to their destination, this would mark Iran’s first oil exports for two months.

Data indicates that the blockade has cut Iran’s crude exports to the lowest amount in six years at 260,000 barrels per day in May, significantly lower than the 2025 average of 1.67 million barrels per day. The US had previously indicated that enforcement of the blockade could happen outside of the Gulf region.

Following the announcement of the US deal with Iran, there has been a noticeable increase in activity among Iranian-linked tankers and cargo ships globally. This includes two other crude oil tankers, Dan and Sinopa, which began broadcasting their positions in the Strait of Malacca, suggesting a broader reactivation of Iranian shipping operations.
