The Colombian government is close to signing a historic peace agreement with the Revolutionary Armed Forces of Colombia (FARC) rebel group.

So far, they have reached a deal on three of the five points on the agenda: rural development, the future political participation of FARC, and how to deal with the illegal drug trade.

Colombian President Juan Manuel Santos says he expects to sign the peace deal before the end of March, and a full bilateral ceasefire is in the works.
