Itanagar, May 13: The fields and roads of Lumla in Tawang district of Arunachal Pradesh was covered with a white carpet of ice after hailstones of marble size pounded the circle headquarters around 3 pm on Saturday. The hailstorm that lasted for an hour forced the people to run for cover. It was particularly severe in Mangdam village. "We never witnessed such huge hailstones earlier and it was really terrifying," Sonam Topgey, a resident of Sazo village under Lumla, said. "This is a warning from mother nature that human beings have distorted and dis-balanced nature's equilibrium," Sonam Thinley, a local SSA teacher added. Reports of crop fields being damaged have surfaced though no casualties of life and properties have been reported. Lumla administration, headed by ADC RD Thungon, is accessing the situation, an official release stated on Sunday.
