The supply of cluster munitions to Ukraine will have serious consequences for the country’s civilian population for decades, Cambodian Prime Minister Hun Sen wrote in a tweet on July 9.
Your interpretation of what the Pentagon said does not match the quote. They are very careful: they cannot definitively conclude that the video includes the uses of cluster munitions. That’s not to say that the video doesn’t show cluster munitions or that Russia isn’t using them elsewhere.
The second link does conclude that Russia has used cluster munitions. That is with the benefit of over a year to gather evidence.
Ukrainian forces have used cluster munitions that caused deaths and serious injuries to civilians. Russian forces have extensively used cluster munitions, causing many civilian deaths and serious injuries.
Not according to the Pentagon, no: “Commenting on videos depicting alleged Russian cluster munition use, DOD officials stated during a March 1, 2022 press conference that “we’ve seen the same video that you have but we have not assessed that it is definitive with respect to the use of cluster munitions. So we are not in a position to confirm the use of cluster munitions at this time.” In a similar manner, a DOD official stated during March 3, 2022, press conference that DOD was still unable to confirm Russia’s use of cluster munitions.”
Ukraine on the other hand has been using cluster munitions against civilians for quite a while now:

From your link:
Here is Pentagon again as of July 6, 2023: Brigadier General Pat Ryder: “I would note that the Russians have already been employing cluster munitions on the battlefield, many with very – which included very high dud rate reportedly.”
Also cluster munitions used by Russia
I wouldn’t be surprised if both sides have been using them.
