The death-toll from sunstroke has risen to at least 22 in eastern India although the grueling heat wave sweeping across many parts of the country is abating, authorities said. Snehlata Bhuyan, deputy secretary with Orissa state's disaster management department, told CNN that authorities have investigated 92 deaths suspected to have occurred from sunstroke since the middle of March. "Of them, 22 are confirmed from heat wave until now," she said. In its latest bulletin, the India Meteorological Department predicted temperatures were likely to fall by two to three degree Celsius in the next three days because of rains and thunderstorms in the country's northwest and east regions.
