Apart from prominent spots in the country, sensitive installations like nuclear plants, military bases, refineries, and hydroelectric dams will be covered during the drills on air-raid warning sirens, civilian training for a "hostile attack" and cleaning of bunkers and trenches

The Ministry of Home Affairs has asked all states to conduct the drills due to the "new and complex threats" that have emerged amid rising tensions with Pakistan following the Pahalgam terror attack

The authorities in all states will involve students of educational institutions, employees of government and private organisations, hospital staff, railway and metro officials, besides uniformed personnel of the police, paramilitary and defence forces, while conducting the mock drills

According to a home ministry communication, the measures to be taken during the drills include the operationalisation of air-raid warning sirens, training civilians on civil-defence aspects to protect themselves in the event of a "hostile attack" and cleaning of bunkers and trenches

The other measures are provisions for crash-blackout measures, early camouflaging of vital plants and installations and updating and rehearsing evacuation plans
