The UN Security Council has endorsed the tenuous ceasefire in Ukraine.
In approving the new resolution, the Security Council is also raising concerns about the continued fighting around the town of Debaltseve.
This is a key rail-hub which neither the government or the rebel fighters are willing to give up.
Observers from the OSCE have been denied access to the region.
OSCE spokesperson Michael Bociurkiw.
"Unfortunately we did not get to Debaltseve. The Special Monitoring Mission to Ukraine didn't get to Debaltseve. This is the third day already of the ceasefire. Attempts will continue, of course."
The ceasefire was inked last week following marathon meetings among the leaders of Ukraine, Russia, Germany and France.
It was supposed to take effect on Sunday.
