Jihadists in Syria pose a direct threat to Russia, Putin has told a defense meeting in Moscow, adding that any targets threatening the country's military there should be destroyed. Defense Minister Sergey Shoigu said Islamic State’s influence in Syria continues to expand.

[CORRECTION: An earlier copy of this story stated that more than 5,000 members of the Free Syrian Army have been operating on the terrorists’ side, according to Vladimir Putin. This was reported as per a wire issued by Sputnik, which was later corrected to Putin's actual words, in which he said that over 5,000 members of the Free Syrian Army have been fighting AGAINST the terrorists. We have also corrected our report and apologize for this mistake.]

The Russian military’s actions in Syria are being coordinated with Russian special services such as the FSB, who are disclosing terrorist cells, including Islamic State, Putin said.

All forces threatening Russian servicemen in Syria should be destroyed, according to the Russian president.
