YARI PLAINS, Colombia (AP) — Leaders of the Revolutionary Armed Forces of Colombia have given their unanimous support to a peace agreement reached last month with the government.

The rebel leader known by the alias Ivan Marquez made the announcement Friday at the conclusion of a week of deliberations by the guerrillas in a remote rural area of southern Colombia. It was the FARC's last conference as a rebel army and was supposed to provide a roadmap of how the group would compete electorally once it turns over its weapons to United Nations-sponsored observers over the next six months.

But in a brief press conference, Marquez didn't provide details about the new political movement being formed. He didn't take questions from reporters.

President Juan Manuel Santos and FARC leader alias Timochenko are expected to sign the agreement Monday in the Caribbean city of Cartagena in an event that will be attended by more than a dozen regional heads of state, U.N. Secretary General Ban Ki-moon and U.S. Secretary of State John Kerry.
