The implications of a strike on the filtration station "go beyond the immediate endangerment of workers serving the basic needs of their community," said Ambassador Apakan.
"An environmental disaster cannot be excluded either, with chlorine tanks at the plant potentially exposing the wider area to the release of poisonous gas," he said.
"As well as demonstrating that the sides have not withdrawn weapons, as they promised they would, the shelling of the filtration plant shows a complete disregard for human life and the wider interests of the civilian population," said Apakan.
"The sides must, at a minimum, immediately cease fire, withdraw weapons proscribed by the Minsk agreements, and disengage from around this critical civilian infrastructure," said the OSCE SMM chief.
