TEHRAN, Iran — Iran has reported a single-day record of more than 5,000 coronavirus cases.

Iran’s health ministry reported 322 deaths, pushing the death toll over 31,000. The new cases on Tuesday eclipsed the previous high of 4,830 last week.

Hospitals in the hard-hit capital of Tehran are overflowing. The increase comes after Iranians packed cafes and restaurants at vacation spots during recent national holidays and the re-opening of schools last month.

The government closed museums, libraries, beauty salons, schools and universities in Tehran earlier this month and imposed a mask mandate outdoors.

Iran officials have resisted a total lockdown because they don’t want to further weaken an economy already devastated by unprecedented U.S. sanctions. The Trump administration re-imposed economic sanctions on Iran after withdrawing in 2018 from Tehran’s nuclear accord with world powers.
