Four Arab nations have cut ties with Qatar
Iran — long at odds with Saudi Arabia and a behind-the-scenes target of the move — immediately blamed U.S. President Donald Trump for setting the stage during his recent trip to Riyadh.
Gulf Arab states and Egypt have already long resented Qatar's support for Islamists, especially the Muslim Brotherhood which they regard as a dangerous political enemy.
The coordinated move, with Yemen and Libya's eastern-based government joining in later, created a dramatic rift among the Arab nations, many of which are in OPEC.
