Russia's intervention in Syria

The Russian military launches cruise missile strikes from the Mediterranean on ISIS positions in Al-Raqqah, the Islamic State of Iraq and the Levant's de facto capital in Syria, Aleppo, and Idlib. A U.S. official confirms that Russia has conducted a significant number of strikes in Syria using both sea-launched cruise missiles and long-range bombers. Russian President Vladimir Putin has pledged to escalate his military campaign in Syria after it was confirmed that a bomb brought down Metrojet Flight 9268 over Egypt's Sinai Peninsula.
