Iran's regular army has begun a two-day ground and air military exercise aimed at upgrading its combat readiness and increasing its deterrence against possible attacks.

According to State TV, the drills involve forces in a wide region in western Iran near the Iraqi border. It showed troops parachuting from helicopters near the towns of Sarpol-e Zahab and Qasr-e Shirin, about 700 kilometers (430 miles) west of Tehran.

Iran, especially the country's Revolutionary Guard, has recently increased military exercises as international tensions grow over its alleged nuclear weapons program, and Israeli officials have said that they have not ruled out military strikes.

Iranian generals have several times warned that in the event of an Israeli attack, the country would deploy its missiles, which with a range of 2,000 kilometers could strike Israel.

The generals had also warned that the country could close the Strait of Hormuz in the Persian Gulf, a strategic waterway for global oil export. The government however has consistently denied such a scenario would take place.
