The Peruvian government has imposed a state of emergency in five counties of the highland state of Apurimac in southern Peru in an effort to curb a sharp increase in Maoist guerrilla violence. The emergency gives the military direct governing powers. It also restricts individual rights to travel freely and permits authorities to make searches without warrants and detain suspects for long periods without filing charges. Among other recent attacks, the Maoist Shining Path guerrillas struck a police post in Apurimac state last week, killing three officers and wounding four others. The state, about 300 miles southeast of Lima, is one of Peru's most impoverished zones.
