TEHRAN - Iran began 10 days of naval exercises in the Strait of Hormuz on Saturday, raising concern about a possible closure of the world's most strategic oil transit channel in the event of any outbreak of military conflict between Tehran and the West.
The military drill, dubbed "Velayat-e 90", comes as the tension between the West and Iran is escalating over the Islamic state's nuclear program.
Some analysts and diplomats believe the Islamic Republic could try to block the strait in the event of any war with the West over suspicions it is seeking atom bombs. Iran's arch-foes Israel and the United States have not ruled out military action if diplomacy and sanctions fail to rein in Iran's nuclear work.
Iran says it wants nuclear energy only for peaceful ends.
