DUBAI (Reuters) - An air strike by a Saudi-led military coalition killed 26 people at a hotel and an adjoining market in Yemen s northern Saadah province on Wednesday, according to medics and a Reuters witness. The attack, which struck the Sahar district of the vast territory that borders Saudi Arabia, demolished the budget hotel and reduced market stalls outside to a heap of twisted sheet metal. Medics retrieved corpses from the rubble.  The military alliance led by Saudi Arabia has launched thousands of air strikes against Yemen s armed Houthi movement, which hails from Saadah and now controls much of the country. The coalition said in a statement carried on state news agency SPA that it was looking into media reports of the strike and would release its findings after a comprehensive review. The 2-1/2 year war effort has yet to achieve its goal of restoring to power the internationally recognized government, but the conflict has unleashed one of the world s worst humanitarian crises and killed at least 10,000 people. Saudi Arabia and its allies, which receive logistical and intelligence help from the United States, accuse the Houthis of being a proxy of Iran.  The Houthi group denies those charges and says it is conducting a patriotic resistance against outside aggressors in thrall to the West.
