Efforts Ramping Up to Resolve Yemen Conflict Following Saudi Attacks Dale Gavlak AMMAN - Efforts to resolve the nearly five-year conflict in Yemen are increasing following drone and missile attacks on Saudi oil facilities last month. Despite Houthi rebel claims of carrying out the sophisticated airstrikes, most Gulf observers believe the highly coordinated attacks on the Abqaiq and Khurais crude oil production hubs were likely launched by Iran. They say regional players and the West see the imperative to prevent a broader conflict with Iran from developing. The conflict pits Saudi coalition forces that support Yemen's government against the Iranian-backed Houthi. Tehran has continued to deny any role in the attacks. The Houthi rebels aremembers of the Zaidi branch of Shi'ite Islam, to which at least one-third of Yemen's population belongs. Theonce rag-tag rebels have, with Shi'ite Iran's help, held off the military might of Yemen's rich Gulf neighbors, Saudi Arabia and the United Arab Emirates, for the past four-and-a-half years. They also have proven to be some of the most effective fighters in the proxy war playing out between Sunni Muslim and Shi'ite powers for control of the Gulf. .
