A notice circulating on social media about a 'Civil Defence Mock Drill on Hostile Attack' in Delhi today at 8 PM has caused concern among residents. The notice, confirmed by the District Magistrate of North East Delhi, states that the drill aims to test the city's preparedness for emergency situations, with no actual threat present. Authorities will conduct the exercise, which includes a planned blackout in specific areas, coordinated actions by police, disaster response teams, and civic agencies. During the drill, air raid sirens will sound across the city, and residents are expected to follow blackout protocols. This exercise is part of routine civil defence measures mandated by the Union Home Ministry to enhance emergency readiness in light of evolving security challenges. Similar drills have been conducted previously under initiatives like Operation Abhyaas. Residents are advised to remain calm and rely on official communication for updates, as the drill is a simulation to improve response systems rather than an indication of danger.
