Iranian officials say overnight US strikes destroyed a desalination facility supplying drinking water to about 10,000 people.

Hamzeh Pour, chief executive of the Hormozgan Water and Wastewater Company, said US strikes hit desalination pumps and electrical infrastructure in Bunji village, in Jask, cutting off water supplies to 20 villages.

"The supply of drinking water to 20 villages with a population of approximately 10,000 people has been completely disrupted," Pour was quoted by Iran's Tasnim News Agency as saying.
