Armenia deputy PM’s office chief Serge Sisserian has resigned after Nikol Pashinyan's Facebook post.

Earlier, Armenian Prime Minister Nikol Pashinyan wrote on his Facebook: “Today I watched dozens of videos of soldiers from the front line. I'm amazed at the guys' shrewdness. You guys are right. I am waiting for you in Yerevan. To finally resolve the issues of whining under the walls.”
