Colombia and the country’s second-largest rebel group announced that they will hold peace talks, heightening expectations for a definitive end to a half-century of political violence in the Andean nation.

The government has been in exploratory talks in Ecuador with the National Liberation Army, or ELN, for more than a year. Negotiators for the two sides announced at a news conference in Caracas, Venezuela, that those talks will now be formalized around a six-point agenda, including justice for victims, disarmament and reintegration into society.
