The Qatar conference, starting on Sunday, aims to raise billions of dollars to rebuild the region, devastated by 10-year of conflict - but money alone is not enough to restore peace and stability. The Liberation and Justice Movement is an umbrella organisation of minor rebel factions whose members signed a peace agreement with the Sudanese government in Doha in 2011. It was expected to be a significant step towards peace, but some major rebel factions rejected the deal. The Doha peace deal is seen as a cornerstone of international efforts to end the violence, but the hundreds of thousands of refugees forced to flee say they can go home only when they are compensated for their losses.
