Ukraine crisis: Prisoner swap boosts ceasefire

Ukrainian government and rebel forces have exchanged dozens of prisoners, a week after a ceasefire came into effect in the east of the country.

A total of 139 Ukrainian soldiers were freed and 52 rebels.

The exchange is the first step carried out successfully under the terms of the 12 February Minsk agreements, brokered by France and Germany.

Later on Saturday the rebels reportedly agreed to begin a pullback of heavy weapons, another key part of the truce.
