KATMANDU, Nepal -- Government forces attacked rebel training camps and hide-outs in the remote mountains of Nepal, killing at least 28 guerrillas on Sunday.

The latest government offensive came a day after a five-day nationwide strike ordered by the rebels ended. The strike shut down most of Nepal in the first two days, but businesses reopened as people responded to the government's call to defy the rebels. Guerrillas have waged an insurrection since 1996 in an attempt to topple the constitutional monarchy in the Himalayan kingdom.
