Long-standing tensions among members of the Gulf Cooperation Council (GCC) that intensified over the past two weeks have culminated in several Arab governments suspending relations with Qatar. The current crisis has roots in multiple areas in which GCC states do not see eye to eye, including in their attitudes toward Iran, their manifold perspectives on supporting political Islamists and the degree of economic and strategic rivalries among them. On June 5, Saudi Arabia, Egypt, the United Arab Emirates and Bahrain announced they would suspend diplomatic relations with Qatar, which has long bucked the Saudi line on condemnation of Iran and support for Islamist groups such as the Muslim Brotherhood.
