Worth noting that while you might be able to make a functional weapon with 60% enriched uranium, it would depend on technical skill and it would also be very large and very sensitive to any design, production, or handling errors. Ie, not reliable.

Normally practical nuclear weapons require at least 90% enriched U, and north of 95% for a compact efficient weapon. Little Boy was >90%.

I'd hazard a guess that if IR wanted to detonate a bomb at a fixed location as a test/demonstration, they could probably do that. If they already tried and failed, we might not even know, if it was underground. But I doubt they would even try that, since it would invite consequences from IL for sure.

In order to deliver a weapon via TBM or using one of their long-range heavy bombers (oh wait...), they still have some work to do.

If I was IL, I'd be concerned that they'd build a large crude bomb, load it on a merchant ship, sail it through the Red Sea and Suez, and detonate in the Med off TLV. But IL doesn't need me to figure that out.
