Russian President Vladimir Putin suggested on Monday that Saudi Arabia should purchase advanced air defence systems from Russia in light of recent drone attacks on Saudi oil infrastructure.

"... In order to protect ... their country, we are ready to provide appropriate assistance to Saudi Arabia, and it is enough for the political leadership of Saudi Arabia to make a wise state decision, as the leaders of Iran did before, having purchased the S-300, or as [Turkish] President [Recep Tayyip] Erdogan did, purchasing the latest S-400 Triumph air defence systems from Russia. They will reliably protect any infrastructure in Saudi Arabia," Putin told reporters at a joint press conference following Russia-Turkey-Iran summit on Syria.
