Attack risks rise for tankers as Iran vows to block more Hormuz routes - Reuters

The risk of attacks on oil tankers navigating the Strait of Hormuz has increased after Iran announced it will block additional shipping routes through the narrow waterway. Iranian officials said the move is intended to pressure foreign vessels that they consider to be violating the country's maritime restrictions.

The heightened threat comes as the region recorded the largest number of tanker attacks in a single week since the Iran–Iraq war began. The surge in incidents has raised concerns among shipping companies and insurers about the safety of vessels transiting the strategic chokepoint.

Maritime authorities and naval forces operating in the area have warned that the situation could further deteriorate if Iran expands its blockade efforts. They have urged ship operators to exercise heightened vigilance and to follow any routing instructions issued by naval patrols.

The Strait of Hormuz, through which a significant share of the world’s oil supply passes, is a critical conduit for global energy markets. Disruptions there can have immediate effects on oil prices and supply chains, prompting international calls for de‑escalation.

While Iran’s pledge to block more routes marks an escalation in its maritime strategy, the exact number of vessels affected and the specific routes targeted have not been disclosed. Stakeholders continue to monitor the developments closely as the risk environment evolves.
