Delhi, the host city for the upcoming G-20 summit, is now under extremely tight security measures. As world leaders gather for the event, various security forces including the Air Force, Paramilitary, Marks Women, NSG, and CAPF have taken control of the city. They are closely monitoring the skies with anti-drone systems. India's Defence Research and Development Organisation (DRDO) is also playing a role in ensuring security during the G-20 summit in New Delhi, scheduled for September 9-10. DRDO has deployed a drone countermeasure system in the diplomatic area to enhance surveillance and safety.
