Russian and Ukrainian peace negotiators held a 90-minute video call on today and working groups will continue to meet throughout the day, a member of the Ukrainian delegation said.
The Kremlin said the talks had made no significant progress as yet, although Ukrainian delegate and lawmaker David Arakhamia was quoted in the Ukrainian media saying that they would be "working the whole day".
Ukraine started the day by defying a Russian demand that its forces lay down arms before dawn in Mariupol, where hundreds of thousands of civilians have been trapped in a city under siege and already laid to waste by the bombardment.
