Central African Republic's interim President Michel Djotodia has resigned at a regional summit aimed at ending violence that has engulfed the country. PM Nicolas Tiengaye also resigned at the meeting in Chad. Thousands of people took to the streets in CAR's capital, Bangui, most of them celebrating the news. Mr Djotodia, CAR's first Muslim leader, seized power last year. Since then 20% of the population have fled fighting between Christian and Muslim militias.
