BOGOTA, Colombia (AP) -- Colombia's president is sending his older brother to Cuba for a meeting with the top FARC rebel commander in hopes of tackling remaining hurdles to peace.
Juan Manuel Santos said Enrique Santos was in Havana Friday as his "personal messenger" to speak with Timoleon Jimenez.
Enrique is a former director of El Tiempo, Colombia's top newspaper. He has been involved in key junctures in the talks, which formally began three years ago.
The president said Friday that he is proposing that negotiators sequester themselves until they resolve outstanding issues.
Still to be settled is how the Western Hemisphere's last remaining major insurgency will demobilize and disarm.
The president wants that to happen by March 23. The rebels have not accepted that date.
