Ukrainian hackers from informal communities called Flame Falcons and Trinity penetrated the website notorious for Russian-backed separatist forces propaganda, 'Anna-News'.
The main page of the resource now shows a video clip with a speech of a masked man.
"If you are watching this video, we have cleared the information space from another website of Russian terrorists," says a video message.

The hackers also appeal to the Ukrainian society to consolidate efforts against Russian aggression.
