Public security authorities called on Sunday for a stronger police presence on the streets and more proactive measures to handle emergencies, following two recent knife attacks that led to deaths and injuries of innocent people and triggered several false rumors that had people running in panic in some cities.

Public security departments should organize armed forces to patrol regularly on the streets, and they should beef up scrutiny in public places, including bus and train stations, airports, subways, schools and shopping areas, according to an online statement released on Sunday by the Ministry of Public Security.

The ministry urged police to respond to the public's calls for help at any time and to respond rapidly to all kinds of emergencies.
