The website containing the report of the assassinated Russian opposition leader Boris Nemtsov about the Russian troops in Donbas was under a powerful DDoS-attack. This follows from the message left in the Facebook by the member of federal political council of the Russian party "RPR-Parnas" Ilya Yashin.
The report consists of 11 sections, among others are "Why Putin needs this war," "How they took Crimea," "Russian military in the East of Ukraine," "Who commands Donbas," and others.
