India summoned a senior U.S. diplomat to protest a military strike on a commercial oil tanker off the coast of Oman [1].

The incident threatens to strain diplomatic relations between New Delhi and Washington while highlighting the volatility of commercial shipping lanes in the Middle East.

The strike occurred June 10, 2024, in the Gulf of Oman near the Strait of Hormuz [1, 2]. The U.S. military action disabled the vessel, which some reports identify as the Settebello [3].

A total of 24 Indian crew members were on board the vessel at the time of the attack [4]. Search and rescue operations successfully recovered 21 of the sailors [1], but three Indian crew members remain missing [3].

The Ministry of External Affairs summoned the U.S. charge d’affaires to lodge a formal protest [1, 2]. Indian officials said they demanded the protection of commercial shipping, and the maintenance of free navigation in the Strait of Hormuz [1, 2].

New Delhi is seeking an immediate de-escalation of tensions in the region to prevent further casualties among merchant mariners [1, 2]. The government said it has requested clarity on the circumstances that led to the strike on a commercial vessel [2].

The Gulf of Oman serves as a critical transit point for global energy supplies. Any military action that affects non-combatant shipping increases insurance premiums and risks for the thousands of Indian nationals working on commercial ships worldwide [1].

Three Indian sailors are missing after a U.S. military strike disabled a commercial oil tanker.

This diplomatic friction underscores the precarious balance India must maintain between its strategic partnership with the U.S. and its need to protect its citizens in high-conflict maritime zones. By summoning the charge d'affaires, India is signaling that the safety of its merchant navy is a non-negotiable priority, regardless of U.S. security operations in the region.
