spokesman for the US Secretary John Kirby

The spokesman for the US Secretary of State has raised concerns about "some of the rhetoric coming out of Turkey with respect to American involvement or support, tacit or otherwise, for [the] ... assassination [of the Russian ambassador in Ankara]," NYT reported Wednesday.

John Kirby called any such claims ludicrous and false.

"We need to let the investigators do their job and we need to let the facts and the evidence take them where it is before we jump to conclusions," Kirby added.

"But any notion that the United States was in any way supportive of this or behind this or even indirectly involved is absolutely ridiculous."

A Turkish Foreign Ministry official, speaking on condition of anonymity in line with government rules, earlier said that Foreign Minister Mevlut Cavusoglu told Kerry that both Turkey and Russia "know" that a movement led by US-based Muslim cleric Fethullah Gulen was behind the attack.
