The second round of talks was even shorter than the first and didn’t address any substantive issues to ending the three-year conflict.

Russia and Ukraine began a major prisoner exchange, swapping hundreds of soldiers and civilians in the first phase of an exchange that was a moment of cooperation in otherwise failed efforts to reach a ceasefire in the 3-year-old war.

Ukraine and Russia agreed to another large-scale prisoner swap but little else during a second round of direct peace talks that lasted just over an hour as air attacks by both sides continue in Europe's largest and deadliest conflict since World War II.
