Devotees were seen taking a dip in the Yamuna river near Kalindi Kunj in Delhi on the first day of Chhath puja today as alarming white, toxic foam covered the river. The water of the river, considered holy, is barely visible in grim visuals shared by news agency ANI. On Chhath - a festival dedicated to the Sun God and mainly celebrated by the people from Bihar, Jharkhand and bordering areas in Uttar Pradesh - devotees gather and take a holy dip in water bodies during the four-day festivities.
