"Curfew will continue in Zadibal and Nowhatta police station areas and Urdu Bazaar police post area as a precautionary measure," a police spokesman said.
He said the decision to continue curfew has been taken to prevent clashes and any possible loss of life or property.
Authorities had on Wednesday imposed curfew in nine police station areas of the city following sectarian clashes in Hawal area.
The curfew was lifted on Saturday but restrictions were again imposed in Hawal and adjoining areas after fresh clashes broke out in the area.
