A 16-year-old boy was killed when a Maoist activist shot at a group of protesters during a strike in southeastern Nepal, an official said on Saturday. The clash occurred late on Friday when protesters stopped a vehicle carrying former Maoist rebels -- whose leaders are now members of Nepal's provisional parliament -- in Lahan, 125 km (80 miles) southeast of the national capital, Kathmandu. District official Chiranjibi Adhikary said one of the Maoists opened fire on the protesters, killing the boy, Reuters reported.
