MUMBAI (REUTERS) - Indian Prime Minister Narendra Modi made an unscheduled visit to a Sikh temple in New Delhi on Sunday (Dec 20), kneeling down in respect and freely taking pictures with visitors at a time when the community is leading massive protests against his farm reforms.

Sikhs in India and abroad have rallied against recent deregulation of agriculture markets that they fear would erode farm incomes by giving a greater say to profit-chasing private companies, instead of assuring a minimum price like in government-regulated wholesale markets.

Protesting farmers, mainly from Sikh-dominated Punjab and neighbouring Haryana, have blocked highways into New Delhi for the past three weeks demanding a repeal of the laws, which the government says widens the agriculture market and are crucial to boost storage and other infrastructure.

The protesters have repeatedly rebuffed Mr Modi and his ministers' attempts to reach a compromise, in what has become the biggest challenge from the country's farmers in his six-year rule.

On Wednesday, a 65-year-old Sikh priest committed suicide at one of the protest sites. The farmers have called for a 24-hour rotating hunger strike from Monday among protesters at home and abroad.

Mr Modi, whose security detail often keeps him far away from the general public, prayed at the Gurudwara Rakab Ganj Sahib, interacted with Sikh religious leaders there and obliged visitors seeking to take pictures with him.

The temple near the Parliament House was where Sikh saint Guru Teg Bahadur was cremated.

"I felt extremely blessed," Mr Modi said on Twitter.

While some social media users and his party colleagues welcomed Mr Modi's visit to the shrine like a "common man, without any restrictions", others urged him to try and end the protests where tens of thousands of farmers, many in their 60s or above, are sleeping in the open in the cold.

"A request to @narendramodi please visit #FarmersProtests site as well where #Farmers are peacefully protesting," a Twitter user posted.
