Iran is extending a night-time traffic curfew to 330 lower-risk cities and towns in an effort to sustain a recent decline in the number of new coronavirus infections and deaths, state television reported.

Alireza Raisi, spokesman for the national coronavirus task force, said on state TV that a curfew running from 9pm to 4am — already in place in 108 “orange,” or medium-risk, cities — will be extended to lower-risk “yellow” areas today.

The curfew, under which the use of private cars is banned to reduce the level of contacts between people, resulted in nearly 100,000 fines on one night in the past week.
