AlHijjah 3, 1436, Sep 17, 2015, SPA -- UN Secretary-General Ban Ki-moon is outraged about reports that Burkina Faso President Michel Kafando, Prime Minister Yacouba Isaac Zida, and several government ministers have been detained by soldiers from the presidential guard, his spokesperson said Wednesday. "The Secretary-General calls for their immediate release," the spokesperson said in a statement. "This incident is a flagrant violation of Burkina Faso's Constitution and Transitional Charter." "The United Nations stands firmly behind the transitional authorities and President Kafando. The Secretary-General notes the strong support of the people of Burkina Faso for a peaceful transition and urges compliance with the transitional calendar, including the upcoming elections," the statement said.
