Doctors Without Borders (MSF) said Saturday that a woman had been killed in an ambush on its team in the Central African Republic, with the medical charity already reeling from the murder this week of three staff in Ethiopia. MSF's Western and Central Africa branch said on Twitter that the woman, who was accompanying a patient being transported by MSF staff near the town of Batangafo, was shot dead after the convoy came under "an ambush by armed men". bdl-dyg/kjl/jj
