Russian President Vladimir Putin accuses Turkey's leadership of collaborating with extremists.
"Turkey's current leadership does not fight radicals as much as it collaborates with them," Putin says in a nationally televised show in which he answers questions from the Russian public.
In southern Turkey, "there is actually a civil war," Putin says. "International society is trying not to notice it, but this is a fact. There is heavy weaponry - tanks, artillery."
Putin adds that it is unsafe for Russians to visit Turkey and Egypt because of security concerns.
