Russian President Vladimir Putin invited Saudi Monarch Salman Bin Abdel Aziz to make his first-ever visit to Russia during a phone call late Monday. The two sides discussed the recent developments in the Yemeni crisis. The two leaders reviewed the bilateral relations and pledged deeper cooperation on international and regional issues, the Kremlin said in a statement. King Salman expressed his gratitude to Putin for his country's decision to abstain during the UN Security Council vote that imposed an arms embargo on the Houthi rebels in Yemen, the Kremlin said.
