The late Saturday report by ILNA did not specify the cause of the blast. It says it also damaged several cars and shattered windows of nearby buildings including a hotel in Imam Khomeini port, some 1,000 kilometers (620 miles) southwest of Tehran.
The port, one of Iran’s major import and export terminals, is located in oil-rich Khuzestan province, the scene of occasional protests in recent years by members of Iran’s Arabic-speaking minority seeking more rights.
Iran in the past has blamed explosions in the province on saboteurs tied to Arab and Western intelligence agencies.
