A French aid worker in Central African Republic was shot and killed in Monday while traveling to a town facing poor health conditions, humanitarian group Doctors Without Borders said according to The Associated Press. Logistics specialist Elsa Serfass, 27, had been traveling from the group's regional base in the African country as part of an «exploratory mission» of the health conditions in the town of N'Gaoundal, the Paris-based organization said in a statement. Doctors Without Borders _ or Medecins Sans Frontieres in French _ said the killing was a «shock» for the group. It said health conditions are «catastrophic» in N'Gaoundal. The town has been a site of fighting between rebels and government forces that has uprooted as many as 280,000 people, according to figures from the United Nations and the international Red Cross.
