Part One: After 52 years Farc rebels have lain down their weapons in Colombia. But the legacy of death and upheaval left by their conflict with the central government present a major challenge to future peace. Former Tanaiste Eamon Gilmore, now EU envoy to the Columbian peace process, explains how the settlement is designed to punish and reintegrate perpetrators without jeopardising the hard-won peace.

Part Two: From Irbil, capital of Iraqi Kurdistan, Ruadhri Giblin reports on a city with aspirations to westernise and modernise. But there are innumerable barriers to Kurdistan's progress, not least that their Peshmerga fighters will soon be taking part in an assault on Isis-controlled Mosul, just 50 miles away.
