Four-year-old Lokendra and his 11-year-old sister Shanti were both seriously injured in the explosion Tuesday afternoon at Tudidhara of Manakot village in Bajura district, some 700 km west of Kathmandu, the Royal Nepalese Army Public Relations Directorate said at a press release.
Lokendra died soon after he was brought to the hospital. No adults were present in the house at the time of the explosion, the army noted, adding, "Both Lokendra and Shanti were taken to the hospital in Martadi, the district headquarters, on Tuesday night after their parents returned from work."
Shanti, who sustained head injuries, is undergoing treatment and reported to be out of danger, the army added.
Over 12,000 Nepalese people have been killed since the anti- government insurgency took place in the Himalayan kingdom in February 1996.
