Iran's air force reportedly fired an "unknown" drone on Friday morning for allegedly breaking its airspace.
The drone was reportedly struck early in the morning in the port city of Mahshahr, which is in the oil-rich Khuzestan province and located on the Persian Gulf.
“The desecrated queen was definitely a foreign country. Its wrecks have been recovered and investigated, ”Khuzestan Governor Gholamreza Shariati said, according to the official IRNA news agency.

He said the drone violated Iran's airspace but did not provide any further information, including whether it was a military or civilian drone.
Iran's Arabic language al-Alam TV channel said: “Residents of Imam Khomeini port city heard the sound of a missile fired on Friday morning. "
An American military official told Fox News on Friday that all American drones are being reported and no one has been shot down.
The Pentagon official, when asked if any US drone crashed or did not work in the region on Friday, said: "There is no reporting of operations on any (US) drone going down."
There was no immediate response from Iran's enemy Israel.

In June, Iran shot down a US surveillance drone in the Strait of Hormuz. Tehran said the drone "violated" its territorial airspace, while the United States called the missile fire "an unprovoked attack" in international airspace over the narrow mouth of the Persian Gulf.
Regional tensions remain high over Tehran's collapsing nuclear power deal with world powers, which the United States unilaterally withdrew over a year ago.
