Indian farmers dig in for reform protests

Sandeep Singh, 65 years old, now spends his nights at the back of his tractor, despite Delhi's bitter winter cold.

The farmers are cooking, eating, praying, singing, protesting and sleeping, all on the highway, resolute about maintaining the blockade until Prime Minister Narendra Modi's government reverses course.
