The Iranian army has launched an annual infantry drill involving 12,000 troops, some 340 kilometers south of the capital Tehran.
State TV quoted Gen. Nozar Nemati as saying the two-day exercise will unfold over about a 500-square kilometer area in the central Isfahan province.
He said the ground forces will practice new offensive tactics.
Iran regularly holds exercises to display its military preparedness and has vowed to respond strongly to any attack by Israel or the United States, both of which view it as a regional menace.
