"We are already witnessing an unbearable catastrophe with the fighting in Blue Nile and South Kordofan in Sudan, and the ensuing outpouring of refugees into South Sudan and Ethiopia."

Writing from Addis Ababa at the start of an Elders delegation to Sudan and South Sudan, Desmond Tutu blogs for CNN about the region's urgent humanitarian needs and what he hopes the Elders can achieve on their visit.

This blog is based on Archbishop Tutu’s contribution to a debate hosted by the Forgiveness Project. He was joined by Mary Kayitesi Blewitt, who lost over 50 members of her family in the Rwandan genocide of 1994, Jo Berry, the daughter of Sir Anthony Berry who was killed in the IRA Brighton bombing in 1984, and by Pat Magee, a former IRA activist convicted of the bombing.

During the filming of their documentary on the search for missing persons in Cyprus, Desmond Tutu exchanged his views on remembrance and reconciliation with his fellow Elders and the young Cypriots travelling with them. For Archbishop Tutu, forgiving the transgressions of those you once considered the enemy is to bring peace inside your own heart.

Ahead of his return to Cyprus, Desmond Tutu blogs about achieving peace and reconciliation through honest dialogue.
