The UAE and Saudi-led forces are preparing an offensive to break the siege of Mareb by the Houthi/Saleh forces. The strategic city is in the center of the country. It lies 200 km (125 miles) to the east of the capital Sanaa, with a major highway running through it, connecting the capital to points east.
