The OSCE on Saturday denounced as "disgraceful" rocket strikes on a Ukrainian government-held port that killed 30 people shortly before pro-Russian insurgents announced the launch of a major new assault.
The pan-European security group charged with observing the conflict said its Ukrainian mission leader Ertugrul Apakan viewed "the shelling in Mariupol... as a reckless, indiscriminate and disgraceful attack aimed at a heavily-populated residential area whose victims included women, children and the elderly."
