MOSCOW - Kremlin Spokesman Dmitry Peskov said Sunday that he could "neither confirm nor deny" reports of a conversation between Russian President Vladimir Putin and US President Donald Trump regarding Ukraine, TASS news agency reported.

"As the administration in Washington unfolds its work, there are many different communications. And these communications are carried out through different channels," TASS quoted Peskov as saying.

"And of course, given the multiplicity of these communications, I personally may not know something, not be aware of something. Therefore, in this case I can neither confirm nor deny it," he added.
