In 1980, the Carter administration provided $60 million in aid to Nicaragua under the Sandinistas, but the aid was suspended when the administration obtained evidence of Nicaraguan shipment of arms to El Salvadoran rebels. In response to the coming to power of the Sandinistas, various rebel groups collectively known as the "contras" were formed to oppose the new government. The Reagan administration authorized the CIA to help the contra rebels with funding, armaments, and training. The contras operated out of camps in the neighboring countries of Honduras to the north and Costa Rica to the south.
