An Iranian official, Mohsen Rezaei, warned that US military bases in Europe could be targeted if President Donald Trump orders new attacks against Iran. Speaking to Al Mayadeen, a news channel associated with Hezbollah, Rezaei stated that any base used by American aircraft is vulnerable to attack. This threat follows Trump's comment suggesting future strikes on Iran are unlikely due to recent political losses.
