A woman places flowers near the site of an explosion in a regional administration building in the eastern Ukrainian city of Luhansk June 3, 2014. Two people were killed and several injured in the explosion which separatists controlling the eastern city said was the result of an air strike by the Ukrainian military. This was denied by Kiev, which said it was caused by separatists who had launched a heat-seeking rocket at a Ukrainian plane but the missile had zeroed in instead on the rebel-occupied regional administration building.
