My comment from the other thread on the same subject:
They havent released anything to prove it, like sat photos, so this is likely based on a single video floating around on the internet, by someone claiming to be a Russian Soldier, firing artillery that they also claim is going into Ukraine.
If the claim is based on this video that was floating around on Twitter yesterday:

Note that there are no leaves on the trees, and the grass is brown. In mid-summer?
As far as the claim that they intend to give the Rebels Heavier Rocket Launchers, Id say it is likely, since there are numerous videos of Kiev using the heavy Smerch launchers against the rebels.
There was even a claim last week that Kiev had launched a Surface-to-surface Scarab-B from Kramatorsk into the refinery at Lyshyansk (sp??), but that didnt go anywhere.
There is supposedly another vid floating around with the same claim that I saw yesterday.
So you are saying that Col Warren would make a statement like this based on Twitter without having other evidence:
The Russian military fired artillery rounds into eastern Ukraine on Thursday, a clear escalation of hostilities there, Army Col. Steve Warren, a Pentagon spokesman, said.
Russia has about 12,000 troops on the border with Ukraine, Warren said. Russian tanks, artillery and rocket launchers have crossed into Ukraine to support separatists there.
This is a clear escalation, Warren said.
The Russians have conducted artillery attacks on Ukraine military targets for the last several days, Warren said.
