US forces board sanctioned oil tanker in Indian Ocean as Iran ceasefire deadline looms

In a statement, the Pentagon said personnel carried out a “right-of-visit” interdiction on the vessel, identified as the M/T Tifani, adding that the boarding was completed without resistance. The department characterised the tanker as “stateless,” despite records indicating it was sailing under a Botswana flag.

Tracking data indicated that the vessel was moving through the Indian Ocean, positioned between Sri Lanka and Indonesia at the time of the operation. Officials did not disclose the precise location or timing of the boarding.

The development comes shortly before the current ceasefire between United States and Iran is set to expire, with uncertainty continuing over whether negotiations will resume. Pakistan is engaged in efforts to facilitate dialogue between the two sides.

US authorities have increasingly focused on intercepting vessels suspected of supporting Iran’s economy or military supply chains. The Pentagon said such actions are part of a wider effort to disrupt networks involved in moving oil and other materials linked to Tehran.

What the statement says

“As we have made clear, we will pursue global maritime enforcement efforts to disrupt illicit networks and interdict sanctioned vessels providing material support to Iran — anywhere they operate,” the statement said, adding that international waters do not shield such vessels from enforcement measures.

Military officials have indicated that these operations will extend beyond the Middle East. Dan Caine, chairman of the Joint Chiefs of Staff, said recently that US forces in multiple regions would be tasked with identifying and intercepting vessels connected to Iran, regardless of where they are operating.

He noted that enforcement activity would include areas outside traditional zones of conflict, including routes linked to the Strait of Hormuz, a key passage for global energy shipments. Ships that departed prior to the implementation of maritime restrictions may also be subject to monitoring and potential interdiction.
