Iran is considering launching attacks on US military targets in Europe if President Donald Trump escalates the conflict, according to a report.

Sources close to Iran’s government told the Financial Times that potential targets included a British air base in Cyprus that was targeted by a drone in March.

Other countries in southeastern Europe such as Bulgaria, which approved US access to its Bezmer air base for refuelling last month, were also weighed up as a potential target for strikes.

It follows warnings that Tehran is considering switching to a “fully offensive” strategy, a senior Iranian official told Reuters on Monday.
