Kremlin Spokesperson Dmitry Peskov affirmed on Monday that the Russian military is not striking civilian buildings and infrastructure facilities in Ukraine, pointing out that the cause of the collapse of a residential building in the city of Dnipro was Kiev's interceptor missile.

"The Russian armed forces do not strike residential buildings or civilian infrastructure facilities, strikes are carried out against military targets," Peskov made clear.
