Russia says Saudi Arabia ' s King Salman bin Abdulaziz Al Saud is scheduled to visit Moscow in the middle of March following the kingdom ' s signal that it is prepared to deploy troops in Syria. Russian Presidential Aide Yuri Ushakov told RIA Novosti on Wednesday that the visit is planned for “mid-March." Ushakov added that an agenda for the visit has yet to be set. The announcement comes as Saudi Arabia, a staunch supporter of the Takfiri militants operating in Syria to overthrow the government of President Bashar al-Assad, has voiced readiness to participate in any ground incursion in Syria if the US-led coalition decides to launch such an operation. Saudi Arabia is already a member of the US-led coalition that has been conducting air raids inside Syria since September 2014 without any authorization from the Syrian government or a UN mandate. The Saudi offer was condemned by Russia, with Pavel Krasheninnikov, a deputy of Russia’s State Duma, warning Riyadh that any military ground operation in Syria would amount to a declaration of war. Syria has also warned the Persian Gulf kingdom against such a move. “Let no one think they can attack Syria or violate its sovereignty because I assure you any aggressor will return to their country in a wooden coffin,” Syrian Foreign Minister Walid al-Muallem said last week. Damascus accuses Saudi Arabia, Turkey and Qatar of funding and arming terrorist groups operating inside the country, including Daesh.
