Former Contra rebels attacked a police station Friday, leaving three guerrillas dead and 35 people wounded in one of the most violent anti-government clashes in months, a Cabinet official said.

Interior Minister Carlos Hurtado said nine of those wounded were police officers in Nueva Guinea, a small town about 190 miles southeast of Managua. The identities of the others wounded were not known, but Hurtado said the casualties were all rebels.The attack followed a week of protests in eastern Nicaragua over the economic policies of President Violeta Chamorro and her administration's ties to leftist Sandinistas.
