How many sources would you need to see the truth?
DONETSK Ukraine/MOSCOW (Reuters) - Russia threatened Ukraine on Sunday with “irreversible consequences” after a man was killed by a shell fired across the border from Ukraine, an incident Moscow described in warlike terms as aggression that must be met with a response.
Although both sides have reported cross-border shootings in the past, it appears to be the first time Moscow has reported fatalities on its side of the border in the three-month conflict which has killed hundreds of people inUkraine.
Kiev called the accusation its forces had fired across the border “total nonsense” and suggested the attack could have been the work of rebels trying to provoke Moscow to intervene on their behalf. The rebels denied they were responsible.

You seem to have a problem gathering information and determining truth (at least on this subject).

Again...Reuters is reporting what Russia claimed happened and they are reporting what Kiev said happened. Reuters did not witness what happened.
