I don't think so. Russia has been cutting undersea cables for some time now, perfecting the techique. Search for 'russian yacht Ragnar' for example.

I didn't find anything sea cable related to this yaht. I found a possible scenario in the UK Sun, but no actual report for an actual cutting. Actually, the Sun Article mentions that cutting such cable will have to be answered with torpedoing the submarine responsible or a cyber attack.

Just cutting cables is silly. More like that they are also tapping the cables.

If it was cut, it was most likely an accident.
