AKIPRESS.COM - Yemen's newly-appointed Vice President Khaled Bahah, a widely respected figure named this week to shore up the legitimacy of the exiled Saudi-backed government, said on Thursday he hoped to avert a Saudi-led invasion to restore unity to the country.

Arab military exercises planned for Saudi Arabia have raised speculation that Riyadh is considering land operations in Yemen, after three weeks of air strikes that failed to halt advances by Shi'ite fighters now in control of most of the country.

President Abd-Rabbu Mansour Hadi named Bahah, a former prime minister and diplomat, as his deputy this week in an attempt to widen support for his government, now exiled to Saudi Arabia since the Iran-backed fighters, known as Houthis, seized the capital and launched a lightning advance on the south.

Bahah is one of the few figures in Yemen whose popularity crosses regional and sectarian lines. Speaking in the Saudi capital Riyadh at his first news conference since taking the post, he said: "We are still hoping that there is no ground campaign announced with the air campaign."

The Houthis, who have formed an alliance of convenience with army units loyal to former Yemeni president Ali Abdullah Saleh, seized the capital Sanaa in September and then advanced toward the southern port city of Aden.

Establishing the government's legitimacy is central to the Saudi-led campaign to drive back the Houthis and prevent Iran from gaining influence. Iran denies allegations that it provides direct military support and funding to the Houthis.

With the Houthi advance showing no sign of slowing, the prospect is growing that Saudi Arabia and its Arab allies could launch a land war in Yemen, the poorest country in the Arabian Peninsula. The leading Sunni and Shi'ite Muslim powers in the Gulf, Saudi Arabia and Iran, are already backing opposing sides in proxy conflicts in Syria and Iraq, reports Reuters.
