The Ministry of Home Affairs on Monday directed all states and union territories to conduct mock drills to check preparedness against "new and complex threats". 

The direction came amid tension with Pakistan over the Pahalgam terror attack.

The ministry's statement said the drills will be carried out at the 244 categorised civil defence districts across the country on May 7.

None of the cities of Jharkhand figure in any one of three category list of districts.However, Delhi figured in category one of the three categories list.

The home ministry's notification said the mock drills will check preparedness for the operationalisation of air-raid warning sirens and train civilians on civil-defence aspects to protect themselves in the event of a "hostile attack".

The mock drills will entail crash-blackout measures, early camouflaging of vital plants and installations and updating and rehearsing evacuation plans.

The mock drills will also include the operationalisation of hotline and radio-communication links with the Indian Air Force (IAF), testing the functionality of control rooms and shadow control rooms.
