In June 2017, Saudi Arabia cut all diplomatic and trade ties with its neighbor Qatar in dramatic circumstances, shunning the peninsula.
The Saudis, backed by six Gulf states who consider Saudi to be the regional hegemon, accused Qatar of supporting terrorists, and siding with Iran, Saudi Arabia's arch nemesis.
