Why has eastern Ukraine returned to full-scale conflict?
Fighting started in April 2014 and raged for months until
Ukraine and the separatists came to a deal on 5 September to halt the
violence and free prisoners.
But the ceasefire never held entirely. Although the intensity
of the conflict subsided, the clashes never really ended and both sides
used the relative lull to build up their forces.
Battle raged for control of the ruined airport at Donetsk,
with Russian-backed rebels trying to seize a strategic and symbolic
asset.
A new rebel push began with the start of the year, culminating in the capture of the airport's main terminal on 22 January.
International observers said the shells that killed 30 civilians in Mariupol were fired from rebel areas
Violence has flared the length of the September ceasefire line and the casualties mounted:
- Civilians were killed by shells and rockets in rebel-held areas, particularly the cities of Donetsk and Luhansk
- Thirty people died in the Ukrainian port city of Mariupol, in
an artillery attack that international observers said came from
rebel-held areas
- Rebels launched a concerted attack to seize the town of Debaltseve, a transport hub held by government forces
Why did the ceasefire break down?
Each side
accused the other of tearing up the peace deal.
For the government, it was the rebels' decision to hold their
own local elections in November 2014, in defiance of the Kiev
authorities.
The separatists, however, were unhappy that the government
had responded by saying it would scrap the special status of their two
regions, Donetsk and Luhansk.
Among the
terms of the truce
were a commitment to pull back heavy guns from the front line by at
least 15km (9 miles), a release of prisoners and an agreement for
international observers to monitor the truce and a buffer zone on the
Ukrainian border with Russia.
Ukraine would also grant wider self rule to Donetsk and Luhansk.
Long story short...things are heating back up.
