Saudi military buildup on Yemen border

Saudi Arabia has moved significant mechanized infantry forces with heavy military equipment including artillery to its southern border with Yemen, since Iran-backed Houthi rebels seized the Yemen town of Taiz over the weekend. The Saudis appear poised to intervene in the civil war in defense of President Abd-Rabbu Mansour Hadi, who fled to Aden following the rebel takeover of Sanaa the capital.
