BBC: Iran has been displaying its military power at a ceremony to mark the country's annual army day.
Speaking at the parade, President Mahmoud Ahmadinejad said Iran was the most powerful nation in the world.
The country's strength was such that no major power would dare to challenge its security, he said.
Official media claimed the ceremony included the largest ever show of aerial strength, with a fly past by almost 200 aircraft.
There was also a huge military parade, with missiles displayed on trucks.
