Kuwait’s Ministry of Health has confirmed 13 deaths from methanol poisoning linked to locally made alcohol. Since Saturday, 63 people— all of Asian nationality—have been treated, with many in intensive care. Thirty-one required ventilators, 51 underwent emergency dialysis, and 21 suffered permanent vision loss, Xinhua reported.

Authorities say the alcohol was sold by Asian individuals in Jleeb Al-Shuyoukh, Farwaniya, located southwest of Kuwait city. Ten suspects have been arrested. Alcohol is banned in Kuwait, with strict penalties for production or sale.
