Iran threatens strikes on Europe in case of involvement in the conflict.
A spokesperson for Iran’s Foreign Ministry stated that Tehran would regard any “defensive actions” by European countries within the framework of a potential U.S. and Israeli operation as an act of war.
According to media reports, Iranian missiles are capable of striking targets in Bulgaria and Romania, where U.S. bases are located. If Iran took-out the base in Romania, that would directly benefit Russia because the Romanian Base is where NATO logistics are located that are arming Ukraine.
If the declared range of the Khorramshahr missile reaches 3,000 km, a significant part of Europe — including Germany and Italy — could fall within its potential strike zone. See map:
