An explosion blamed on communist rebels killed a high school student and injured two others in Nepal, while soldiers gunned down at least three suspected guerrillas in stepped-up operations against the insurgents, officials said Monday. Hundreds of supply trucks, meanwhile, defied a rebel-called general strike and moved in and out of the capital Katmandu under military escort. Monday was the third of an 11-day nationwide strike to protest the Nepali king's seizure of power and imposition of emergency rule earlier this year. Police said they suspect Sunday night's bomb was left by rebels at a market in Pokhara, a resort town 200 kilometers (125 miles) west of the capital, Katmandu. The explosion killed a student and two others were hospitalized with injuries, a police official said on condition of anonymity. The Royal Nepalese Army headquarters in Katmandu said soldiers killed at least three rebels in Dang, about 400 kilometers (250 miles) southwest of Katmandu.
