Donald Trump says US held productive ceasefire talks with Russia

President Donald Trump says the United States has held productive discussions with Russia about a ceasefire and that the conflict with Ukraine could come to an end.

While Russian President Vladimir Putin says he supports the idea of a halt in fighting, he says he has conditions.

Ukraine claims Moscow is trying to drag out negotiations in the hope of making further gains on the battlefield.

The US Secretary of State Marco Rubio says he is cautiously optimistic about the chance of a deal.
