Clinton heads to Ebola-stricken Uganda, S. Sudan

US Secretary of State Hillary Clinton flew out of Senegal Thursday and headed to Uganda before a visit to the world's newest nation South Sudan, locked in a crippling border and oil dispute with Sudan.

Her 11-day tour takes in seven African nations.

In Senegal, Clinton hailed the west African nation as an example that "democracy can prosper on the continent".

She said she had a "productive, comprehensive" discussion with President Macky Sall.

"I want to thank him for taking time to discuss a number of issues - economic issues, regional, security issues, issues that the United States is very committed to assisting Senegal on addressing."

Clinton will also visit Kenya, Malawi, South Africa and finish her trip by attending the state funeral of Ghana's late president John Atta Mills on August 10.
