Russia and Ukraine were meeting in Istanbul on Monday for peace talks, the second round of negotiations since the adversaries resumed direct dialogue two weeks ago.

The two sides are expected to formally exchange their respective conditions for a cease-fire, but expectations for the talks are low.

Moscow and Kyiv are talking under pressure from President Trump, who has alternatively cajoled and chided the leaders of both countries. But Russia and Ukraine have been holding firm, with neither expected to present terms that are acceptable to the other side.
