“A service building at a power and water desalination plant was attacked as part of the Iranian aggression against the State of Kuwait,” the Gulf state’s electricity ministry said.

The attack caused “the death of an Indian worker and significant material damage to the building,” the statement added, without elaborating on the location of the facility.

Kuwait’s military said later on Monday that it had intercepted 13 hostile drones in the past 24 hours, with “major damage” caused to the building at the power and water plant.

The oil-rich Gulf has borne the brunt of Iran’s attacks in response to US-Israeli strikes that sparked the Middle East war.

Tehran has threatened to target vital infrastructure across the Gulf, including energy sites and desalination plants on which the desert countries rely heavily for their water supply.

However, in a statement on Iranian state television on Monday, Iran’s military accused Israel of launching the attack “under the pretext of accusing the Islamic Republic of Iran”.

Saudi Arabia, Qatar and Oman have condemned the attack on the Kuwaiti plant, with Riyadh and Doha blaming Iran.
