At least two fully laden Iranian tankers have successfully navigated past a US naval blockade in the Persian Gulf this week, delivering roughly 9 million barrels of crude oil to global markets. The vessels were part of a flotilla that maneuvered around warships to complete their shipments, demonstrating Tehran's ability to circumvent sanctions.

This operation marks a significant challenge to US efforts to restrict Iran's oil exports, which have been a cornerstone of Washington's maximum pressure campaign. The tankers reportedly went dark - disabling their tracking systems - to avoid detection while sailing through international waters. Such tactics have become increasingly common as Iran seeks alternative routes to maintain its crude exports.

The successful delivery of this oil cargo could provide crucial revenue for Iran's economy, which has been battered by sanctions and reduced oil sales. Market analysts note that while the volumes are relatively modest compared to Iran's pre-sanctions exports, they represent a persistent challenge to US enforcement efforts.
