An Israel-affiliated merchant vessel was struck by an uncrewed aerial vehicle off India’s west coast, British maritime security firm Ambrey said on Saturday, in the first such known attack so far away from the Red Sea since the Gaza war.

A fire on the Liberian-flagged tanker was extinguished without crew casualties in the incident 200 km (120 miles) southwest of the Indian city of Veraval, it said, adding some “structural damage was also reported and some water was taken onboard”.

“Merchant vessels are advised these types of attacks are typically targeted at Israel-affiliated shipping, but have in the past mistakenly hit previously Israel-affiliated vessels,” Ambrey said.

An Indian Navy official told media that it responded to a request for assistance on Saturday morning.

“The safety of crew and ship has been ascertained. The Navy has also dispatched a warship to arrive in the area and provide assistance as required,” the official said, declining to be named as he was not authorised to discuss the incident.

“The vessel has crude oil and was going towards Mangalore from a port in Saudi Arabia. As per inputs received, the fire has been extinguished but it has affected its functioning. The ICGS Vikram was deployed on the patrol of the Indian Exclusive Economic Zone when it was directed towards the merchant ship in distress. All the crew are safe, which includes around 20 Indians. The ICGS Vikram has alerted all ships in the area to provide assistance to it,” Indian media quoted defence personnel as saying.

The incident involving an unmanned aerial vehicle striking an Israel-affiliated merchant vessel in the Arabian Sea comes amid heightened tensions and increased drone and missile attacks in the Red Sea by Houthis. The group claims to be supporting Palestinians in Gaza under siege by Israel.
