Iran yesterday launched a series of large-scale military exercises aimed at introducing the country's new defensive doctrine, state-run television reported.
The television report said the military exercise would occur in 14 of the country's 30 provinces and could last as long as five weeks.
The first stage of the maneuvers began with air strikes in the southeastern province of Sistan va Baluchistan, the report said.
The military exercises come as Iran faces heightened international scrutiny because of its contentious nuclear program and for supporting the guerrilla group Hezbollah in Lebanon.
Iran has denied Israeli accusations that it is arming and training Hezbollah fighters but also has declared Hezbollah victorious in its battle against the Jewish state, which ended on Monday when a UN ceasefire resolution went into effect.
The Islamic Republic, which views the US as an arch foe, also is concerned about the US military presence in neighboring Iraq and Afghanistan and Israel's threats to destroy its nuclear facilities.
The military exercise, involving 12 infantry regiments, is called "The Blow of Zolfaghar," in reference to a sword that belonged to Imam Ali, one of the most revered figures of Islam for Shiite Muslims. A majority of Iran's 70 million people are Shiite.
Iran has routinely held war games over the past two decades to improve its combat readiness and test locally made equipment such as missiles, tanks and armored personnel carriers.
