The sectarian tensions between Sunnis and Shiites in the Middle East worsen as the Saudi government of the royal family executes a Shiite cleric, Baqr al-Nimr, involved in Arab Spring related protests in Saudi Arabia calling for change in the country to improve the conditions of minorities. The continuing war in Syria with the support of Iran, the involvement of Russia and bombing of Turkey related ethnic groups, worsen tensions in the Middle East. The Obama administration's efforts to work with Russia to bring a peaceful resolution to the Syrian civil war, cited by WP's correspondent Liz Sly, may have lost credibility with Sunni states because of Russia's bombing campaign in Syria and on the border with Turkey.
