ADEN - A senior leader of Yemen's Houthi movement said on Thursday that Saudi air strikes amounted to an aggression against the country and warned they would set off a 'wide war' in the region. 'There is an aggression underway on Yemen and we will confront it valiantly,' Mohammed al-Bukhaiti, a member of the Houthis politburo, told the Doha-based al Jazeera television. 'Military operations will drag the region to a wide war.'
