Kremlin says no date yet for next round of Ukraine peace talks

The Kremlin said on Thursday there was no progress yet towards setting a date for the next round of peace talks with Ukraine, Interfax news agency reported.

Another agency, TASS, quoted Kremlin spokesman Dmitry Peskov as saying Russia was in favour of continued U.S. efforts to mediate.

Resuming negotiations after a gap of more than three years, Russia and Ukraine held face-to-face talks in Istanbul on May 16 and June 2 that led to a series of prisoner exchanges and the return of the bodies of dead soldiers.

But they have made no progress towards a ceasefire which Ukraine, with Western backing, has been pressing for.
