India has summoned a senior US diplomat after American forces struck the Palau-flagged tanker Settebello in the Gulf of Oman, leaving three Indian sailors missing. The vessel, carrying 24 Indian crew members, was reportedly targeted by US Central Command during an operation linked to the enforcement of sanctions on Iranian oil shipments. While 21 Indian crew members have been rescued, search operations for the missing sailors are ongoing with support from Omani authorities. New Delhi summoned US Deputy Chief of Mission Jason Meeks and expressed concern over the attack, stressing that commercial shipping and civilian infrastructure should not be targeted. The incident comes as US President Donald Trump continues to defend American military operations in the region. The strike has raised questions about the safety of international shipping routes and the impact of escalating tensions in the Gulf on Indian nationals working at sea.
