The diplomatic crisis between Saudi Arabia and Iran took another downward turn when Iran accused Saudi Arabia of deliberately targeting its Yemen embassy in an airstrike. Recent hostilities began between the countries after Saudi Arabia executed noted Shi’a cleric, Nimr al-Nimr. In response, Iranian protesters charged and damaged the Saudi embassy in Tehran. We’ll get more on the brewing situation with Juan Cole, professor of history at the University of Michigan. His blog is Informed Comment and he’s author most recently of the book, The New Arabs: How the Millennial Generation is Changing the Middle East.
