Navigation through the Strait of Hormuz saw a notable decline on Sunday, recording its lowest level in about five weeks, amid escalating military tensions between the United States and Iran and continued attacks on ships in the region, heightening concerns over navigational security.

Data from ship-tracking company Kepler showed that only six ships crossed the strait during the day, the lowest number recorded in five weeks.

According to the data, the transiting vessels included the ultra-large crude oil tanker Humanity, carrying about two million barrels of Iranian oil, as well as the tanker Captain Andreas, carrying about five hundred thousand barrels of Kuwaiti petroleum products, while three empty tankers entered the strait in preparation for loading oil cargoes.

The data also indicated that most tankers deliberately turned off their transceivers while transiting the strait, a step reflecting growing security concerns in the vital waterway.
