Amid a water crisis in the national capital, the Delhi Congress held 'matka phod' protests across the city on Saturday with its members smashing earthen pots to the ground. Delhi Congress President, Devender Yadav, told NDTV that we have been cautioning the Central and the Delhi governments over the receding water levels in the national capital as temperature rises and the problems that would follow. We also alerted them about the tanker mafia operating in Delhi.
