The truce in eastern Ukraine appears to be taking hold after more than a week of violence since it first took effect. Pro-Russian separatists have pulled their heavy weaponry from the front lines, a key demand under the ceasefire deal. The Ukrainian military says fighting has stopped, but that it is too early for a pullback of their own following the rebel offensive to take the city of Debaltseve last week. On Tuesday, a rebel leader said his side still aims to control the entire territory of the two separatist provinces, including the port of Mariupol, but to seek this through “negotiations with the Ukrainian side.”
