CNN: Russia conducts first airstrike in Syria (Video)

Russia has conducted its first airstrike in Syria, near the city of Homs, a senior U.S. official told CNN on Wednesday.

The Russians told the United States that they should not fly U.S. warplanes in Syria, but gave no geographical information about where they planned to strike, CNN reports.

The senior official said U.S. missions are continuing as normal.

Vladimir Putin's request to Russian parliament required under country's law was immediately approved, paving the way for "open Russian intervention in Syria."
