Authorities in Delhi will carry out security drills at 55 locations in the city at 4 pm on Wednesday as part of the nationwide civil defence exercise ‘Operation Abhyaas’ directed by the Centre, officials said.

The drill will simulate multiple hostile scenarios like air raids, multiple fire emergencies, and search and rescue operations, among others. Sirens will be sounded by police teams across the 15 police districts in the city as part of the exercise.

On Tuesday, the Delhi Police stepped up security measures and raised barricades at key spots, including Connaught Place and the areas near Parliament.

They procured Long-Range Acoustic Devices (LRAD), capable of transmitting clear messages in a 500 metre to one kilometre radius, and officials have been briefed about their functioning.

“We have identified five sites in each of the 11 revenue districts — a market, a big residential colony, a school, a government office and a hospital. We may not carry out a blackout drill since it will require coordination with the Northern Powergrid and it is not feasible,” a senior Delhi government officer told PTI.
