President Daniel Ortega de-nounced the U.S. government for deciding to give the Contra rebels more non-lethal aid, saying it should instead support regional leaders' plan to dismantle rebel forces.

Later Monday, the Defense Ministry said rebels attacked a military truck in the country's north. It reported two guerrillas and one soldier killed in the Sunday attack near the Honduran border.Ortega, speaking to 60 Harvard scholars from 37 countries, accused the United States of ignoring a Central American peace plan that commits regional leaders to draft a program by mid-May to demobilize Contra forces.
