A land-mine explosion in Nepal on Saturday killed at least six bus passengers and injured several others. Nepalese authorities say the land mine was hidden beneath a barricade blocking a road. It exploded as passengers were working to dismantle the roadblock in a (Kapilvastu) district (325 kilometers) southwest of the capital, Kathmandu. The land-mine is believed to have been planted by Maoist rebels, who fought with government troops in the same area on Friday -- a battle that killed at least five soldiers and an unknown number of guerillas. Nepal's Maoists have been fighting since 1996 to establish a communist republic in the Himalayan kingdom. Violence has continued unabated since King Gyanendra dismissed a coalition government and seized power six months ago.
