India's sword-wielding Sikh warriors guard protesting farmers

Dressed in a signature electric blue long-robe, a foot-long turban, and wielding an antiquated sword and a walkie-talkie, hundreds of armed martial men from the Sikh warrior order of Nihang, paces through a maze of tents, tractors and trolleys that dot the blocked highway on the border of Delhi. They are the self-appointed first line of defence in the ongoing protests between farmers and Prime Minister Narendra Modi’s government.
