Saudi Arabia imposes dusk-to-dawn curfew in battle against coronavirus
The curfew - from 7pm until 6am - will be imposed for 21 days, the official Saudi Press Agency reported, citing a royal order.
The move comes after Saudi Arabia on Sunday said the number of COVID-19 cases had jumped to 511, the highest in the Gulf. The kingdom has reported no deaths so far.
Health sector employees, security and military officials will be exempt from the curfew restrictions, the royal order said.
