CAIRO (AP) — The Egyptian government is seeking ways to conserve oil-powered electricity during the U.S.-Israel war with Iran, enacting at least one policy that threatens Cairo’s identity as a city that never sleeps.The government imposed new nationwide closing times Saturday for stores, restaurants and cafes, ordering them to shut early and interfering with their ability to operate during critical hours. “It’s ruinous,” said Youssef Salah, a cafe owner in Cairo. “It deprives us from our peak time.” The decision is one of a series of measures the government has taken in recent weeks to mitigate the fallout of the U.S. and Israeli war against Iran, which has shaken the Middle East and the global economy. Though Egypt is not a party to the widening conflict, the most populous Arab country is one of the most impacted by the war’s far-reaching repercussions, including higher oil prices and disrupted shipping routes.
