LONDON — A chemical tanker in the Indian Ocean was hit by a drone launched from Iran on Saturday, the US military says.

A fire on board the Chem Pluto was extinguished. There were no casualties.

Iran has not commented. Houthi rebels in Yemen — who are backed by Iran, and support Hamas in its war with Israel — have recently used drones and rockets to target vessels in the Red Sea.

But this event is the first of its kind so far away from there, according to maritime security firm Ambrey.

The same company also said the vessel was heading from Saudi Arabia to India, and was linked to Israel. The Houthis have claimed to be targeting Israel-linked vessels over the conflict in Gaza.

The US said the Chem Pluto was hit by “a one-way attack drone fired from Iran”. It is believed to be the first time the US has publicly accused Iran of targeting a ship directly.

It has previously accused Iran of being “deeply involved” in planning operations against commercial vessels in the Red Sea — a charge Tehran has denied.

However, Iran’s Revolutionary Guards have warned they could force the closure of waterways other than the Red Sea if “America and its allies continue committing crimes” in Gaza.

The Pentagon statement said the Chem Pluto was “a Liberia-flagged, Japanese-owned, and Netherlands-operated chemical tanker”.

It was struck “200 nautical miles (370km) from the coast of India” at 10:00 local time (06:00 GMT).

The hit caused structural damage to the tanker and water was taken onboard.

The incident took place 200 nautical miles south-west of the city of Veraval in India’s Gujarat state, according to United Kingdom Maritime Trade Operations (UKMTO).

Ambrey said the event fell within an area the firm considered a “heightened threat area” for Iranian drones.

The Indian navy sent an aircraft and warships to offer assistance.

In a separate development, the US Central Command (CENTCOM) said that on Saturday “two Houthi anti-ship ballistic missiles were fired into international shipping lanes in the Southern Red Sea from Houthi-controlled areas of Yemen. No ships reported being impacted by the ballistic missiles”.

It also said the USS Laboon warship patrolling the area “shot down four unmanned aerial drones originating from Houthi-controlled areas in Yemen that were inbound” to the American vessel.

Later that day, a crude oil tanker reported being hit by a Houthi drone in the southern Red Sea, while another tanker saw a near miss.

Many large global shipping groups have suspended operations in the Red Sea due to the increased risk of attacks. — BBC
