Saudi Arabia has spent the past year taking actions that have alarmed and angered some of its neighbors, especially Iran. There have been warnings this could provoke a war. So who's driving these policies, and why?
Tensions in the Persian Gulf are high after Saudi Arabia executed a prominent Shiite cleric. Iran sees itself as the champion of Shiite Islam and is furious with the Saudi action. Saudi Arabia has retaliated by cutting off relations.
Saudi Arabia and Iran have never been friends, but their relations went from bad to worse over the weekend. Saudi Arabia and allies Sudan and Bahrain have broken off diplomatic relations with Tehran and ordered Iranian diplomats out of their nations within 48 hours.
