Jharkhand, Dec 19 (ANI): A well orchestrated Maoist attack in Gumla district of Jharkhand left one woman dead and injured two others. The Maoists escaped after sighting a vehicle approaching from the opposite direction. Meanwhile, approximately 160 kilometres away from Ranchi, the Maoists planted a bomb at a petrol pump, which could have caused loss to life and property on a greater magnitude but was diffused by the prompt action of the bomb disposal squad. It was a country-made crude bomb weighing not less than seven kilograms.
