Argentine military aid may soon flow to El Salvador, according to Col. Rafael Flores Lima, the country's military chief of staff. The Colonel told reporters here that the Argentine government has offered such aid to the Salvadoran government.
Monitor Latin America correspondent James Nelson Goodsell reports the Colonel's statement tends to confirm previous reports that Argentina was on the verge of aiding the Salvadoran government in its struggle with leftist guerrillas.
Col. Flores Lima did not specify what kind of aid Argentina would offer, but in the past it has been suggested that Argentina might train Salvadoran intelligence officers and offer anti-guerrilla training to other units of the Army. In other Latin American developments:;
