'Mark Etherington re-joins OSCE SMM as Deputy Chief Monitor, bringing a wealth of experience and skill to better serve the Mission and Ukraine,' reads the message.
Alexander Hug, Etherington's predecessor stepped down on Wednesday. He has worked with the mission since March 2014.
Previously, Hug claimed that the sides in Donbas do not follow the ceasefire regime, this is why he retires with ‘with anxiety and sadness’. He claimed this at the briefing, UNN news agency reported.
‘As anyone who works in OSCE, I have to abandon my office after 10 years of working in the organization. I have been giving short reports on the situation on Donbas almost every week for about 4 years. Believe me, I am not satisfied with what I am going to say, - little has changed in that time. The sides are still violating the agreements on the ceasefire set four years ago,’ Hug claimed.
