Lebanon on Friday began a two-week partial lockdown and nighttime curfew after coronavirus cases increased sharply following an explosion in Beirut that killed and injured thousands of people. On Thursday, Lebanon’s Health Ministry tallied a record 605 confirmed new cases in the previous 24 hours, raising the total registered cases since late February to 10,952. Many businesses were closed Friday morning in Beirut even though some sectors, including banks, groceries, book shops and pharmacies were allowed to open.
