It’s by “a Jordanian-Palestinian politician” but it’s also in the Jerusalem Post: Saudi Arabia is bringing Iran to its knees. This is the opening para:

On January 11, 2016, Iran’s official media confirmed the state had filled the Arak nuclear reactor core with concrete. In short: Iran has killed its flagship nuclear site and its nuclear program is now limited to smaller projects, paperwork, research and, of course, propaganda videos.

Now read the rest. It turns out the bit about Arak is true. This is so extraordinary I have to ask why have I not heard any of it anywhere else before?
