Russia said on Wednesday said it will augment anti-aircraft weapons in Syria and is urging its citizens not to visit Turkey even as the second pilot of a warplane shot down over that country Tuesday was reported alive and well.
Russian President Vladimir Putin says a second pilot from the Russian jet shot down by Turkey near the Syrian border has been rescued.
Putin was speaking in televised comments on Wednesday after Defence Minister Sergei Shoigu told Russian news agencies that the man was rescued in a 12-hour operation which ended in the early hours on Wednesday and is now "safe and sound" at Russia's air base in the government-controlled area in Syria.
The other pilot of the Su-24 jet was reported dead.
Mr Putin meanwhile backed a recommendation from the Foreign Ministry for Russians not to visit Turkey after the downing of the fighter.
"After such tragic events like the destruction of our plane and the death of our pilot, this is a necessary measure," Mr Putin said in televised comments.
Russia's defence minister said Moscow will send its new anti-aircraft missiles to Syria.
Russian news agencies on Wednesday quoted Mr Shoigu as saying that the S-400 anti-aircraft missile systems would be sent to the Hemeimeem air base in the government-controlled area which Moscow uses for its Air Force sorties.
S-400s were first put on active combat duty in Russia in 2007.
