He said the question of building the temple rose long ago but has not been resolved yet because "when the Poklonnaya Hill territory was planned, the mayor's instruction on construction of temples for representatives of different religious beliefs who died during the war had not been taken into account."
Baidakov added that it is unknown when the temple construction will be completed.
Poklonnaya Hill already has an Orthodox church, a mosque and a synagogue.
Russia's four traditional faiths are Orthodox Christianity, Islam, Judaism and Buddhism.
