"Russian peacekeepers are fulfilling their mission," Zakharova told a briefing.
The spokeswoman added that Russia is working to resolve the aggravation between Armenia and Azerbaijan.
"For those who do not know, I would like to remind you that there have been exacerbations before and there have been problems, and the parties blamed each other, and it was the Russian peacekeepers who did everything to stabilize the situation and they succeeded. Therefore, such an attitude towards our peacekeepers is not accepted," Zakharova concluded.
Last week, Armenian Prime Minister Nikol Pashinyan said that Russian peacekeepers allegedly do not fulfill their obligations regarding control over the Lachin corridor, this statement was made despite the efforts of the Russian side to unblock the corridor.
