The fourth round of talks between Russia and Ukraine have begun. Kyiv’s lead negotiator, Mikhailo Podolyak, described negotiations as “hard”. He went on to say he believed Russia "still has a delusion that 19 days of violence against (Ukrainian) peaceful cities is the right strategy."

NewsHour’s Tim Franks joins the programme live from Lviv.
