The Cenepa War between Peru and Ecuador ends on a ceasefire brokered by the UN.

The Cenepa War or Third Ecuadorian-Peruvian War, also known as the Alto Cenepa War, was a brief and localized military conflict between Ecuador and Peru, fought over control of an area in Peruvian territory near the border between the two countries. The two nations had signed a border treaty following the Ecuadorian–Peruvian War of 1941, but Ecuador later disagreed with the treaty as it applied to the Cenepa and Paquisha areas, and in 1960 it declared the treaty null and void. Most of the fighting took place around the headwaters of the Cenepa River.

Peru, officially the Republic of Peru, is a country in western South America. It is bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile, and to the south and west by the Pacific Ocean. Peru is a megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has a population of over 32 million, and its capital and largest city is Lima. At 1,285,216 km² (496,225 sq mi), Peru is the 19th largest country in the world, and the third largest in South America.

Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west.

The country's capital is Quito and its largest city is Guayaquil.

A ceasefire, also spelled cease-fire, is a stoppage of a war in which each side agrees with the other to suspend aggressive actions, often due to mediation by a third party. Ceasefires may be between state actors or involve non-state actors.
