President of India Ram Nath Kovind administered the oath of office and secrecy to Narendra Modi as the country's prime minister on Thursday.
This is Modi's second consecutive term as the country's premier.
The swearing-in ceremony of Modi and his new Council of Ministers is being held at the forecourts of Rashtrapati Bhawan (President House) situated at the Raisina Hill in the Indian capital.
Modi's first term of the prime minister began in 2014.
The key highlights of the swearing-in ceremony were the inclusion of Bharatiya Janata Party (BJP) President Amit Shah and former Foreign Secretary S. Jaishankar in the cabinet, and the exclusion of External Affairs Minister Sushma Swaraj and Health Minister J.P. Nadda in Modi's new government.
Over 45 ministers, including cabinet and junior ministers, are likely to be sworn in at the ceremony which began at 19:00 local time with Modi being the first to take the oath.
The oath-taking ceremony is expected to last around two hours.
