The 1970s saw the rise of two new guerrilla organizations, the Guerrilla Army of the Poor (EGP) and the Organization of the People in Arms (ORPA). They began guerrilla attacks that included urban and rural warfare, mainly against the military and some civilian supporters of the army. The army and the paramilitary forces responded with a brutal counter-insurgency campaign that resulted in tens of thousands of civilian deaths. In 1979, the U.S. president, Jimmy Carter, who had until then been providing public support for the government forces, ordered a ban on all military aid to the Guatemalan Army because of its widespread and systematic abuse of human rights. However, documents have since come to light that suggest that American aid continued throughout the Carter years, through clandestine channels.
