Operation Barkhane is a French military operation launched in August 2014 to combat terrorism in the Sahel region of Africa. It focuses on supporting local forces in countries like Mali, Niger, and Chad to stabilize the area and counter extremist groups, including Al-Qaeda and ISIS affiliates. The operation involves around 5,100 French troops and aims to enhance security and promote peace in the region. It is part of a broader international effort to address the growing threat of terrorism and improve the capabilities of local military forces to maintain stability in the Sahel.
