TEHRAN: Iran's president says the country's armed forces will make the enemy regret any act of aggression against Iran.

Mahmoud Ahmadinejad's remarks came as Iranians on Tuesday marked National Army Day with a military parade.

He did not specify who the enemy is but such language in Iran is a common reference to the West, especially the United States and Israel.

Both the US and Israel have not ruled out a military option against Iran's nuclear facilities, which the West suspects are geared toward making nuclear arms — a charge Tehran denies.

Iran's refusal to halt its uranium enrichment program is its main point of contention with the West.

Ahmadinejad says ''foreign interference will bear nothing but destruction, rifts and insecurity'' in the region.
