According to Ukrainian news site TSN.ua, right-wing politician Dmitry Yarosh said the blast killed about “200 terrorists,” destroyed 20 Grad rockets, and trucks filled with ammunition.  “There was a mushroom cloud over Donetsk,” one of the rebels told Ukrainian news website ZN.ua, adding that “dozens of homes were left without windows.” Ukraine-based Euromaidan PR, a citizen-journalist news website, posted several Twitter updates about the explosion, also saying the Ukrainian army launched the attack on a rebel-held site.
