In the Central African Republic, a rebel leader has declared himself president a day after President François Bozizé fled the country as rebels stormed the capital. The Seleka rebels had accused Bozizé of reneging on a January peace deal. The newly installed president, Michel Djotodia, has vowed to adhere to that accord by sharing power with civilians and loyalists of the former regime. South Africa, meanwhile, says 13 of its soldiers were killed in clashes with the rebels on the outskirts of the capital Bangui.
