Russia and Turkey have signed an arms deal that Turkish President , PM , has said could see a Russian missile system installed by next month . This move is likely to anger the US , which has previously said Turkey can not be in possession of both American F-35 jets and the Russian S-400 anti - aircraft defence systems .
