Iranian Defence Minister Mostafa Mohammad Najjar said that the Iranian armed forces are ready to counter any surprise attack by the enemies with a crushing response, the official IRNA news agency reported.
The vigilant Iranian armed forces are now monitoring all military movements in the region round the clock, Najjar was quoted as saying.
Iran is a powerful country is the region with high military might, he said, adding that recent war games conducted by the armed forces have demonstrated the capabilities of Iranian forces for the world.
Iran's Islamic Revolution Guards Corps (IRGC) completed military manoeuvres in the Gulf called Payambar-e Azam 3 (Great Prophet 3) in mid July to improve combat readiness and capability. Iran successfully test fired new long- and medium-range missiles in the drills.
"The enemies try to conduct a psychological warfare to intimidate us but to no avail," he said.
Najjar comments follow western media reports about an armada of U.S. naval battle groups heading toward the Persian Gulf with the aim of reinforcing U.S. strike forces in the region.
Iranian armed forces are self-sufficient in the production of defence soft and hardware, Najjar added.
IRGC Commander Brigadier General Mohammad-Ali Jafari said last Monday Iran has tested a new advanced naval weapon, which is "unique in the world" and can target the enemy at the range of 300 km.
