Ceasefire period begins in Ukraine
The ceasefire period for fighting in Ukraine has begun, but there are no immediate signs of whether either side in the conflict is observing it.
Under an agreement struck last week, both Ukrainian forces and Russian-backed separatist rebels were to hold their fire as of one minute after midnight on Sunday. If that holds, both sides are to begin pulling back their heavy weaponry to form a wide buffer zone.
Intense fighting persisted around the strategic government-held railway hub of Debaltseve on Saturday, which has been besieged by separatist forces.
Rebels have said they will not consider any battles for the town to be a violation of the ceasefire.
The conflict has killed more than 5,300 people so far.
