In June 2017, the Gulf States Cooperation Council (GCC) erupted the most serious division crisis in its history. Saudi Arabia, the United Arab Emirates, Bahrain, United Egypt, suddenly announced the severance of diplomatic relations with Qatar, and the implementation of the comprehensive blockade of land, sea and air. The crisis is rapidly fermenting in the short term, with the Middle East and the Horn of Africa embroiled in many countries.
