"Israel" has, since its attacks on Lebanon in 2006 and those on Gaza in 2008 and 2014, used a new nuclear weapon, one which kills with a high temperature radiation flash and with neutrons. ...

"Israel" and the USA (at least) have developed what is almost certainly a mini-neutron bomb. "Israel" is using it in Gaza. And may be using it in Lebanon (again).

EDIT: some important criticisms of the author have been raised in the comments. It's quite possible he's speculating too much from insufficient evidence. However, he does offer the following, which we shouldn't dismiss either:

1. Enriched Uranium was found in Gaza according to this Nature article.
2. A crater from an "israeli" bomb in Lebanon was found to be radioactive (original source was an unnamed Lebanese newspaper in 2006, but it was also discussed in this article in The Independent).
3. Samples from the crater were found to contain enriched uranium (independently verified by the Harwell laboratory, as mentioned by The Independent article in 2).
