Ukraine crisis: Heavy shelling continues around Donetsk
There has been heavy shelling around the main rebel city of Donetsk in eastern Ukraine.
It had been hoped that the fall of the strategic town of Debaltseve might allow the fragile ceasefire to take hold but so far there seems no end to the fighting.
The UK Defence Secretary, Michael Fallon, has warned that Russia could use the conflict with Ukraine to destabilise the Baltic states which are part of Nato.
