In the midst of violent conflict in Colombia, humanitarian zones supported by churches and civic groups are a way of stopping the killing and modelling an alternative.

World Council of Churches general secretary the Rev Dr Sam Kobia has expressed "joy" at the liberation of Ingrid Betancourt and other hostages in Colombia - and has called for more humanitarian releases.

In a world where we are used to generalizing, it is inevitable that we will continue to use expressions like “the rich” and “the poor”, says Paul Mukerji. But his time in Colombia led him to question the way this division is formulated.

Paul Mukerji, a tour manager from Kent in England, is travelling to Colombia as part of a delegation sponsored by Christian Peacemaker Teams (CPT), which works to 'get in the way' of violence in zones of conflict around the world.
