In terms of returning fire, that's also forbidden under the Minsk agreements. Only in cases of direct threats or, to be honest—and here we might disagree, but I'm just saying the way that it works—only when our soldiers' lives are threatened directly or have already been lost might we give direction to return fire on the sources of incoming fire. However, this is only in such cases. We try to uphold the Minsk agreements to the utmost.
