It comes after Turkey accused Russia of an "obvious war crime" Monday after almost 50 civilians were thought to have been killed in missile attacks in northern Syria.
The attacks took place in the Idlib province and Azaz near the Turkish border.
Russian President Vladimir Putin's spokesman Dmitry Peskov told reporters the claims made by Turkey were "unfounded accusations", ITV reported.
"We categorically do not accept such statements, the more so as every time those making these statements are unable to prove their unfounded accusations in any way," he said.
