Foreign secretary denounces 'reckless Iran threats' after missiles fired at Diego Garcia

Iran reportedly fired two ballistic missiles at Indian Ocean base, but neither reached the target.

The article kind of downplays the most interesting elements. Not an expert, but to my limited understanding:

* I think this is the longest-range use of a ballistic missile in anger, possibly ever?

* This seems to reveal previously-unknown range of Iranian ballistic missiles and, if true, could touch basically all of Europe?

> * This seems to reveal previously-unknown range of Iranian ballistic missiles and, if true, could touch basically all of Europe?

The Wikipedia article has said they had missiles that can range 4300km since 2019 (as in the article was updated in 2019) https://en.wikipedia.org/w/index.php?title=Shahab-5&oldid=91... . If Wikipedia has known about it for 7 years, surely military planners were already aware.
