A police officer says the fatalities occurred Saturday in the West Bengal state districts of Murshidabad, Burdwan and North Parganas. Twenty people were injured by the lightning. The officer also said Sunday that a 65-year-old woman was killed when pre-monsoon rains caused a house to collapse in Murshidabad district. He said a 31-year-old woman was killed in West Bengal's Nadia district when a tree uprooted by a thunderstorm fell on an auto-rickshaw she was in. Thunderstorms have hit across northern and eastern India this weekend, with monsoon rains likely to hit the southern coast this week. --SPA 12:59 LOCAL TIME 09:59 GMT www.spa.gov.sa/w
