Pentagon questions purpose of Russia's S-300 air defense system in Syria
Pentagon press secretary Peter Cook has said that the Pentagon does not know how Russia is going to use its S-300 anti-aircraft missile system in Syria, according to The Washington Post.
"I would question just what the purpose of the system is," Cook said, The Washington Post reported.
He noted that Russia's declared goal in Syria is to fight extremism, but that the Islamic State group and the al-Qaida branch there don't have planes that could be targeted by such a system.
