Kabila takes over from assassinated father

Joseph Kabila, the son of assassinated Congolese president Laurent Kabila, has been sworn in as his successor.

The president Kabila pledged to unite and defend a country that has been ravaged by corrupt leadership and civil war.

Joseph Kabila is expected to address the nation for the first time. Raised in Tanzania and Uganda, he remains a mystery to most people in Congo, who aren't even certain about his age.
