Colombia: Life inside Colombia's FARC

The leftist Revolutionary Armed Forces of Colombia have been embroiled in conflict with government forces for nearly five decades.

The cat-and-mouse violence was believed to be coming to an end, as government troops killed several of FARC's leaders in recent years - but the rebels, driven into the jungle and mountain regions, have proven far from defeated.

Karl Penhaul, reporting for Al Jazeera, tracked down one of the FARC's fighting units, spending 10 days among them to learn more about their motivations, goals and tactics.
