The successful targeting of the four cables, which are believed to belong to the AAE-1, Seacom, EIG, and TGN systems, marks a serious disruption of communications between Europe and Asia.
I still haven’t seen independent confirmation of the cable cutting from a non Israeli source, nor have I seen indications of a cut line on any of the looking glass servers I’ve checked. This bit is important, because we should be able to independently see the results of a cut sea cable.
I think the overall takeaway is that at least some cables took some kind of damage. Blaming Yemeni rebels might be nonsense, though - other actors in the area might have done it.
Did you look?
Seacom, however, has seemingly confirmed in the African press that it is having cable issues, but didn’t go so far as to point the blame at any group.

This source links to some other sources, some Israeli and some not.

I did, in fact, look. Only your second link, however, is independent confirmation, and I did not see that announcement at the time of my post.
The other two links are to articles reporting what jpost, and globe reported, which is not independent confirmation.
