MT Mercer Street: Iranian drone laden with explosives attacked oil tanker off Oman, US inquiry concludes

The United States announced results of its forensic investigation into last week’s fatal drone attack on a merchant tanker off Oman.

The US military’s Central Command said experts concluded that the Unmanned Aerial Vehicle (UAV) was produced in Iran. The evidence has been shared with explosives experts in Britain and Israel who concurred with the findings.

The attack on the Israeli-operated MT Mercer Street killed two people.

A British security guard, Adrian Underwood, and the ship’s Romanian captain lost their lives as the ship sailed past the Omani island of Masirah.

Britain, the US, Israel and Romania, were quick to blame Iran which has denied any involvement. It said if there was any proof then it should be made public.

Now a statement from Centcom has shed some light on what it says its investigation has revealed.

Throughout the past week an explosive investigations team from the US Navy’s aircraft carrier the USS Ronald Reagan has been examining the evidence left behind by the drone attack.

After interviewing the survivors and studying the explosive residue they have concluded that the ship was targeted by three drones in all.

The first two, launched at the ship on the evening of Thursday 29 July, missed their target. But the third drone, launched early on Friday 30 July and loaded with a military grade explosive, hit the pilot house and exploded, killing the two men and leaving a 2-metre diameter hole.

Investigators say explosive chemical tests had identified the residue as RDX, a nitrate-based explosive, indicating that the UAV was rigged to cause injury and destruction.

The investigators also recovered part of the drone’s wing and after further testing they concluded that the drone was produced in Iran. A joint statement issued by all the G7 nations on Friday condemned Iran’s actions and said its actions threatened peace and stability.

Iran and Israel have been engaged in an undeclared shadow wae for a while now.

Israel is widely assumed to be behind a serious of sabotage acts on Iran’s nuclear programme, including the assassination of key scientists. It has also attacked Iranian ships suspected of carrying oil to Syria that is destined for Iran’s militia ally in Lebanon, Hezbullah.

Iran has been targeting Israeli-linked shipping with limpet mines, something which the Iranian Revolutionary Guards Corps train intensively for. But last week’s deadly drone attack marked a major escalation, killing some of those onboard and dragging in a major western power.
