Officials identified the vessel attacked as the Liberian-flagged oil tanker Pacific Zircon. That tanker is operated by Singapore-based Eastern Pacific Shipping, which is a company ultimately owned by Israeli billionaire Idan Ofer.

While no one immediately claimed responsibility for the attack, suspicion immediately fell on Iran. Tehran and Israel have been engaged in a yearslong shadow war in the wider Middle East, with some drone attacks targeting Israeli-associated vessels traveling around the region.
