A senior Russian official on Tuesday has accused the U.S. of being behind the suspension of its peace negotiations with Ukraine, RIA news agency has reported.

"It was Zelenskyy's Washington curators who contributed to the fact that the negotiations turned into stagnation and are not ongoing," Chairman of the Russian State Duma's international affairs committee Leonid Slutsky was quoted as saying.

But Mykhailo Podolyak, a member of the Ukrainian delegation, voiced his belief that peace talks "will resume."

The most recent round of face-to-face talks between Russia and Ukraine took place in Istanbul on March 29.
