A Mexican diplomat says he has met with the leader of Colombia's second largest rebel group in an effort to broker a peace deal between the group and the Colombian government.

Mexico's Andres Valencia told reporters late Tuesday his talks with National Liberation Army (ELN) leader Francisco Galan focused on ways to reduce differences between the rebels and the government in order to set up a possible meeting between the two sides in Mexico.

The Colombian government is demanding the group disarm and cease its practice of kidnapping citizens.

While other paramilitary groups in the nation have grown rich from the drug trade, the ELN funds itself through kidnapping.
