BOGOTA, Colombia (AP) — Colombia’s delegation to peace talks with FARC rebels is heading back to Cuba to resume negotiations, and its chief says it’s time to accelerate the pace and get some measurable results toward ending the half-century-old conflict.

Humberto de la Calle told reporters Sunday after the team met with Colombian President Juan Manuel Santos that a “faster pace” is needed. He asked society and the leftist Revolutionary Armed Forces of Colombia for help.
