So the bbc article posted upthread says
‘Tehran has previously stated it had unilaterally limited the range of its missiles to 2,000km. But Israel now claims that Iranian missiles have double that range – up to 4,000km. That would put not just Diego Garcia in its sights, but also much of mainland Europe’
Meanwhile The bbc article sites doubts on the range of Irans missile capabilities
The Times has an article with much the same statement re Irans range by the IDF more recently
Maps have been posted showing graphically this information
The air distance from Bakhtaran (now known as
Kermanshah) which is a missile base in western Iran to London, UK, is approximately 3,800 to 4,000 kilometers
There is as yet no evidence that Iran shot any missiles at DG to start this rumour of Irans long range capabilities and
No evidence that the US shot any down
Whats it all about
Israeli spin
or no one knows whose shooting at what
