New Delhi: Bharatiya Janata Party (BJP) president Amit Shah hoisted the national flag on the occasion of 67th Republic Day here at the party headquarters.
Earlier, Prime Minister Narendra Modi had greeted the nation and hailed the contribution of those who framed the Constitution.
The nation is celebrating its 67th Republic Day today and the main function will be held at Rajpath in the national capital where President Pranab Mukherjee will take salute of the parade and French President Francois Hollande will preside as the chief guest.
In view of recent terror attacks in Paris and at Pathankot air base, stringent measures have been taken to avoid any untoward incident.
Security has been tightened in the national capital, particularly around Rajpath and the parade route.
Delhi has turned into a fortress ahead of the Republic Day celebrations.
Multi layered security has been put in place and elaborate ground-to-air security and traffic arrangements have been made.
Barricades have been installed at all exit-entry points and sensitive locations. Around 40000 security personnel have been deployed at key locations in the city, including metros, market places, shopping malls, railway stations and inter-state bus terminals.
