The business partner of the deceased said 20 people worked with him at the mandi, which spreads around 80 acres.

According to the government's decision, vegetables and fruits are being sold from 6 am to 10 pm and thereafter, trucks are allowed to enter the market between 10 pm and 6 am.
The total number of coronavirus cases in the national capital rose to 2,156 on Tuesday, with 75 new cases being reported.
