No date has been set for Saudi King Salman’s visit to Russia, Saudi Press Agency (SPA) reported, citing an official source from the Foreign Ministry.

The source dubbed media reports speculating a date for King Salman’s visit to Russia as “incorrect” as there was no timetable confirmed yet.

Russia’s RIA news agency reported on Wednesday that the Saudi King plans to visit Moscow in mid-March, quoting Kremlin aide Yuri Ushakov.

Russia and Saudi Arabia are backing opposing sides in the Syria conflict, and both countries are major oil exporters.

Meanwhile, the Riyadh-based Islamic Military Alliance, formed by Saudi Arabia to fight extremism, will hold a meeting next month, Al Arabiya TV reported.

The coalition was formed in December 2015, amid the spread of Islamic State (ISIL) militants in Iraq and Syria.

ISIL, also known as Daesh, is a radical Sunni group prohibited in a range of states, including Russia.

Russia has been launching airstrikes against ISIL targets in Syria at the request of Syrian President Bashar Assad since late September.

A US-led international coalition, which includes Saudi Arabia, has been launching airstrikes against ISIL in Iraq and Syria since September 2014.

The Saudi-led anti-terrorism coalition formed in December has over 30 members, including Egypt, Qatar, the United Arab Emirates, Jordan, Turkey, Libya, Yemen, Malaysia, and Pakistan.
