A friend sent me a link but it seems fishy. But...I wouldn't imagine seeing CNN or Fox News report on this until they got their agenda right.
Still digging, but there's talk of a small earthquake being triggered by missile strikes against Iranian military assets in Syria. They admit the reports are unconfirmed. https://www.dailystar.co.uk/news/world-news/699359/syria-attack-missile-war-earthquake-hama-aleppo
Edit: Probably unrelated. Seems this is actually the same location mentioned in the original report, though twitter is the source for both stories near as I can tell. Still waiting on a secondary source. Probably not a nuke, but a big fuel-air bomb or an arms/fuel depot going up could explain it.
Such things have happened in yemen in what looks suspiciously like a neutron bomb. https://www.youtube.com/watch?v=I1ycCiylGiM
Not debating, just adding on...

"The effect is most commonly associated with a nuclear explosion, but any sufficiently energetic detonation or deflagration will produce the same effect."
It's more associated, in the context of physics, with a high-density detonation than specifically a nuclear bomb. A nuclear bomb just happens to be that exact situation, too.
I guess it was confusing of me to link a video that claims it was a nuke, but I think we probably agree that the video was not of an actual nuclear detonation. A video of a weapons depot getting hit with a normal bomb (the official story in this event) can result in an explosion that is pretty much indistinguishable from a small nuke.
And to add on to that, I don't think any sort of nuke burns and smokes before it actually detonates.
One magnitude 4.4 quake in Iran about 22 hours ago: https://www.earthquaketrack.com/quakes/2018-04-29-03-43-36-utc-4-4-10
That's the only other one in the region during the last 24 hours.
