CHENNAI, March 10 — Restaurants and hotels across India warned of disruptions and possible shutdowns today, as the Iran war constricts supplies of cooking gas, prompting authorities to set up a panel to review industry requests.

The fuel shortage comes as the US-Israel war on Iran has halted ship traffic in the Gulf and the Strait of Hormuz, driving up energy prices and transport costs, hitting exports and output from Gulf producers, such as Qatar and Saudi Arabia.
