An Iranian drone attack last week on an Eastern Pacific Shipping product tanker off Oman’s coast left a 75cm-wide hole in the hull, the US military said on Wednesday.

Photographs released by US Centcom, the US military arm responsible for the Middle East, revealed the 50,000-dwt Pacific Zircon (built 2013) was struck just below the main deck on the stern.

The device carried on the drone exploded and went on to penetrate and damage internal compartments, a boiler, water tank and life raft, said the US.
