Kofi Annan, the former UN secretary-general who won the Nobel Peace Prize for humanitarian work, has died in Switzerland at age 80.
On his Twitter account, his family and the Kofi Annan Foundation said he died peacefully on Saturday after a short illness.
Annan, who was chairman of the foundation, left behind a wife, Nane, and children named Ama, Kojo and Nina, who were by his side on his last days.
The family said: "Annan was a son of Ghana and felt a special responsibility towards Africa.
"He was particularly committed to African development and deeply engaged in many initiatives, including his chairmanship of the Africa Progress Panel and his early leadership of the Alliance for a Green Revolution in Africa (AGRA)."
The Ghanaian was key to the peace deal that was struck in Kenya after the 20077/8 post-election violence.
The peace accord signed between President Mwai Kibaki
and Opposition leader Raila Odinga ended the
violence that was sparked by a disputed election.
It saw the birth of the Grand Coalition Government with Kibaki as the President and Raila as the Prime Minister.
Annan described his chief mediator role as the most engaging but noted that it ended a stalemate that left at least 1,000 people dead.
"My role in mediating was amongst the most intensive and enduring of all my interventions," he said in March 2017, nine years after the process.
