That could include action to safeguard Russians living in the North African state of Libya, which has been ravaged by violent ISIS terrorists since the fall of dictator Colonel Gaddafi.
Speaking at the fifth World Congress of Compatriots in Moscow, Mr Putin said: “People who are not in Russia due to various reasons should be firmly sure: we will always protect your interests.”
“Moreover, in difficult and crisis situations, such as in Libya, Syria or Yemen.”

Moscow’s jets carried out 81 strikes on targets belonging to ISIS and other militants across Syria, according to the Russian defense ministry.
Russian bombers “destroyed a large fortified location of ISIS militants,” including an air-defence gun and a tank, a defense spokesman said.
