Ukraine crisis: Artillery fire 'ongoing'
The organisation monitoring the situation in Eastern Ukraine says that the ceasefire is largely holding but there have been reports of artillery fire in areas including Debaltseve and Luhansk.
The Organization for Security and Co-operation in Europe's Michael Bociurkiw in Ukraine also told BBC News that that their teams had been denied access to some areas.
Spokesmen for both the government and the pro-Russian rebels have said some shelling had continued, mainly around the besieged town of Debaltseve.
