Two Iran-linked tankers are sailing eastward through the Strait of Hormuz ahead of the US and the Islamic Republic signing an interim peace agreement on Friday that would re-open the waterway, Bloomberg reports.

The fuel carriers are transiting the chokepoint with their transponders on, according to shiptracking data. The Musik is in the strait, while the Argo Maris has already passed through and is in the Gulf of Oman, but is still within the US blockade line that runs from the easternmost tip of Oman to the Iran-Pakistan border.
