An Indian Navy boat, deployed to help clean the river Yamuna in Delhi, is stuck in the very sewage it aims to remove. The Navy's 'Barasingha' has been docked for over a week at the riverbanks, trapped in the muck and waste in the Yamuna. Visuals show the boat stationed at a spot, with two Navy officers standing guard near the fetid river. The vessel, equipped for desilting, is unable to move because the water is too shallow; any boat needs at least two metres depth to move but because of decades of pollution, the depth is far less in parts of the river.
