Multi-layer security cover in Delhi on Independence Day as PM Modi set to address nation from Red Fort

Giving details of the technology being used to ensure foolproof security, he said, "AI-based facial recognition CCTV cameras have been installed, while anti-drone technology is also being used for security."

"Adequate traffic arrangements have been put in place. The traffic police has also issued an advisory. We urge people to follow the advisory. The borders (of Delhi) have been closed for heavy vehicles from Monday night, while others entering the city are being checked. We are keeping a strict vigil on social media as well," Nalwa said.

The Gyan Path in front of the Red Fort has been decked up with flowers and G20 signage. However, there are no major decorations on the fort's rampart from where the prime minister will address the nation.

The government has invited around 1,800 special guests from across the country to attend the programme. Seventy-five couples from each state and Union Territory, in their traditional attire, have been invited to witness the ceremony.

Sarpanches of vibrant villages, nurses, fisherfolk and labourers engaged in the construction of the Central Vista project are also among the special invitees.

"This year, more than 20,000 officials and civilians are taking part in the Independence Day celebrations. Gyan Path has been decorated with flowers and G20 signage," a police officer said.

Special Commissioner of Police (Special Cell) HGS Dhaliwal said all units of the force are on alert.

"All the checks are being implemented with related agencies. It is a big arrangement and all the units are doing their jobs. The G20 summit will take place in three weeks, due to which there is more sensitivity. We had seen that a week before the Republic Day celebration, anti-national and Khalistan-related graffiti appeared on walls in areas of west Delhi. Two people were arrested in this connection," Dhaliwal said.

Keeping in mind the recent violence in Haryana's Nuh and adjoining areas, a strict vigil is being ensured, police said.

Sharing details of the security arrangements, Special Commissioner of Police (Law and Order) Dependra Pathak said, "Independence Day is being celebrated with full enthusiasm this year with no COVID-19 restrictions in place. Therefore, a robust deployment of police has been ensured." "We are coordinating and sharing real-time information with other agencies," Pathak said.

Following convention, anti-drone systems have been installed at the Red Fort. All anti-terror measures have been initiated, including the setting up of air defence guns. Snipers, elite SWAT commandos and sharpshooters have been positioned at strategic locations for the security of the prime minister and other VVIP guests.

Thorough checking is being carried out at the borders and the police have warned of strict action against anyone trying to disrupt law and order in the national capital.

The areas surrounding the Red Fort have been demarcated as a "no kite flying zone" till the completion of the programme.

As many as 153 kite catchers have been deployed at strategic locations to intercept kites, police said. Residents of areas near the Red Fort have been asked not to fly kites till the event is over.

A kite had landed just below the podium during PM Modi's Independence Day address in 2017. The prime minister, however, had continued with his speech.

Police on Thursday imposed prohibitory orders under Section 144 of the CrPC in areas such as Rajghat, ITO and Red Fort.

They also prohibited the flying of sub-conventional aerial platforms such as paragliders, paramotors, hang-gliders, unmanned aerial vehicles, microlight aircraft, remotely-piloted aircraft, hot air balloons, small-size powered aircraft, quadcopters, and para-jumping from aircraft over the jurisdiction of the National Capital Territory of Delhi up to August 16.
