(CNN)Secretary of State Rex Tillerson spoke by phone with Russian Foreign Minister Sergey Lavrov on Saturday about the situation in Syria following Thursday's strikes on a Syrian air base, Russia's Ministry of Foreign Affairs said in a post on its official Facebook page.
Putin denounced the US strike against the air base as "aggression against a sovereign state in violation of the norms of international law."
"In order to protect the most sensitive objects of the Syrian infrastructure, a system of measures to bolster and increase the effectiveness of the Syrian armed forces' air defense systems will be implemented," ministry spokesman Igor Konashenkov said in a statement carried on state media.
