Despite government efforts to resettle hundreds of thousands of Kenyans displaced from election violence earlier this year, a state-funded human rights group has said too little is being done to address grievances back home.

On May 5, the government launched Operation Rudi Nyumbani (Return Home) to help shuttle thousands of men, women and children back to their homes. And about 40,000 people have returned, according to the Kenya National Commission on Human Rights.

Margaret Warner traveled to Kenya in March 2008, just after the government and opposition had reached an agreement on power-sharing. She reported on the deal and how the country was dealing with the fallout from the political violence.

Stephen Ndegwa, a visiting scholar at the UCLA Globalization Research Center - Africa and a governance specialist with the World Bank, answered your questions about the political dispute in Kenya and whether the power-sharing deal will hold.

The ethnic-driven killings in Kenya -- ignited by disputed elections in December 2007 -- are a sign of long-simmering tensions, and any long-term political resolution must address those deep-seated fissures, regional experts say.
