Russia doesn't reject the possibility of a meeting between President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy, but it can only happen once a document has been agreed upon, Kremlin spokesman Dmitry Peskov said on Tuesday.

Commenting on Bucha killing accusations against Russia, Peskov said they were a "monstrous forgery" aimed at denigrating the Russian army. 

He added that consequent remarks involving President Vladimir Putin were unacceptable as officials, including U.S. President Joe Biden, called for Putin to be put on trial for war crimes.
