Prime Minister Narendra Modi Saturday commissioned India's largest indigenously built warship "INS Kolkata" into the Indian Navy, describing it as "a symbol of our self-reliance in the field of defence".

"INS Kolkata, entirely built in India, is a symbol of our self-reliance in the field of defence. It is a worthy example of the country's technical abilities and will send a strong message around the world," Modi said at the commissioning ceremony held at the naval base here.
