Which emergency powers has Centre asked states and UTs to invoke?
Centre has asked states and Union Territories (UTs) to invoke emergency powers available to them under Civil Defence Rules, 1968. States and UTs can ban/regulate light displays for safety to thwart aerial or night-time attacks. Governments can conduct mock drills in any area, build air raid shelters or order building owners to implement camouflage, like painting rooftops or using nets.
