Stepping over shrapnel in a leafy park in the eastern Ukrainian city of Luhansk, pro-Russian rebel leader Vasily Nikitin gives his version of what happened in the few seconds of violence that killed eight people in broad daylight.
He says the sharp, twisted pieces of metal he and others collected from the grass, off the street, from behind the tires of a blood-smeared white Nissan Maxima is proof the Ukrainian Army shot unguided S-8KO cluster bombs into the park and a nearby rebel headquarters, causing an explosion.
In the worst violence yet in Ukraine's eastern Luhansk province, which included a shootout between rebels and border guards this week, Kiev said rebels caused the blast when they launched a heat-seeking rocket at a Ukrainian plane that instead hit the occupied regional administration building.
