India's push to save its cows starves Bangladesh of beef

Some 30,000 Indian soldiers guarding the border with Bangladesh have a new mandate under Prime Minister Narendra Modi's government this year - stop cattle from crossing illegally into the Muslim-majority neighbor.

Roughly every other night, troops armed with bamboo sticks and ropes wade through jute and paddy fields and swim across ponds to chase aging bovines, and smugglers, headed for markets in Bangladesh.
