UPSC CAPF – 2016
The correct option is B. Operation Sangaris was a French military intervention in the Central African Republic.
Operation Sangaris was a French military operation launched in December 2013 in the Central African Republic (CAR) to restore order and stability amidst sectarian violence. It succeeded the short-lived Operation Boali. In June 2016, France announced that Operation Sangaris would formally end in autumn 2016, transferring security responsibility to the UN peacekeeping mission MINUSCA and Central African forces, while maintaining a smaller presence.
The intervention followed a request from the Central African transitional authorities and was supported by the United Nations. It aimed to disarm militias and support the political transition process. The mission officially ended on October 31, 2016.
