Reserve officer and Israeli activist Eyal Biram has warned "Iran is not afraid to attack the UK" as the prospect of World War 3 looms.
This comes after Israel shot down over 300 drones and missiles sent from Iran over the weekend.
The attack was a retaliation to a suspected Israeli airstrike on an Iranian embassy building earlier this month.
At an emergency UN Security Council meeting on Sunday, envoys from the two countries locked horns over the attacks - with Israel calling for sanctions and further retaliation, Iran claiming the matter had "concluded", and UN Secretary-General António Guterres counselling de-escalation.
Speaking to GB News Biran, who used to work in the Special Forces said: "I think Iran has an achievement a goal.
"Their goal is to create an Islamic caliphate from Iran to Egypt. They will do whatever they can in order to turn the entire into an Islamic caliphate, specifically the Middle East.
"If the UK will prevents them for doing it, they will attack the UK. They're not afraid."
