US President Donald Trump has tightened economic sanctions against Iran, and his administration says it has built up the US military presence in the region.
It accuses Iran of threats to US troops and interests. Tehran has described US moves as “psychological warfare” and a “political game”.
"The Americans have been present in the region since 1833 and they are now at their weakest in history in West Asia," said Rear Admiral Ali Fadavi, a deputy Guards commander, according to Fars.
