France says worried by Ukraine crisis, demands guarantees for observers

PARIS (Reuters) - France's foreign ministry said on Wednesday it was "extremely concerned" by the situation on the ground in eastern Ukraine and demanded guarantees that international observers be allowed to carry out their mission fully.

A ceasefire agreement signed in February 2015 in Minsk that aims to end the conflict between Ukrainian government forces and pro-Russian separatists has failed to end artillery fighting. Each side accuses the other of violating the truce.
