India, March 17 -- The US push for a quick ceasefire between Ukraine and Russia may get more impetus as President Donald Trump might dial Vladimir Putin sometime this week.

White House special envoy Steve Witkoff said on Sunday that the US is continuing its engagement and conversation with Ukraine as well.

"I expect that there'll be a call with both presidents this week. And we're also continuing to engage and have conversation with the Ukrainians," Witkoff said on CNN's State of the Union.

On Friday, Kremlin spokesman Dmitry Peskov said Putin had asked Witkoff to convey messages to Trump ahead of a possible phone call and added there was "cautious optimism" about the prospect of a ceasefire deal, according to the Interfax news agency....
