"Who's there?"

Translation: Кто там?

[sixangryeels]

Это я, почтальон Печкин, принёс заметку про вашего мальчика!

[pablomaclarry]

Кто там?

[oXQL5]

In English, this sometimes implies that someone is in the immediate vicinity, as in more accurately (but not colloquially) "who's here?", especially when one is concerned. So, in such a circumstance, would a Russian specifically say "кто здесь?", or still use там?

[delondir]

You can use both the same way

[zorritas1]

shouldnt the кто be accusative?

[oscar_wildecat]

Why? It's not the object of a verb here.
