THE medical charity Medecins Sans Frontieres (Doctors Without Borders), which was awarded the Nobel prize for peace on Friday, counts Somalia as among the toughest environments it works in. The governemnt in the Horn of African country collapsed in 1991 and since then the usual infrastructure of state, medical facilities included, have crumbled as clans and subclans battle for territorial control. MSF’s current activities in Somalia include war surgery, cholera prevention and treatment as well as measles and tuberculosis programmes and water treatment projects. The prize provides recognition for MSF’s high standards of professional health care as well as the willingness to speak out against violations of humanitarian principles, the charity said.
