MNA � Emphasizing that the recent US harassment of a passenger plane is a gross violation of international law, Iran's Judiciary Chief Seyyed Ebrahim Raeisi called the US action unforgivable.

"The solution to end the US wickedness in the region is to expel them from the region," said Raeisi on Saturday referring to the recent provocation by US warplanes against an Iranian airliner.

"The US harassment of a passenger plane is a gross violation of international law," he added, stressing, "The US action is unforgivable."

"Iran�s Attorney General and the deputy of international affairs of Judiciary will diligently follow up on the complaints of the passengers of this plane," Raeisi added.

Two US warplanes put the lives of tens of Iranian and Lebanese civilians in danger after conducting dangerous maneuvering near Beirut-bound Mahan Air�s Flight 1152 on Syria�s air on Thursday night. The airliner�s pilot reportedly reduces flight altitude to avoid colliding with the warplanes which led to several injuries among passengers.

Iran immediately reacted to the incident, saying it will give a firm response in proper time.

�The Islamic Republic of Iran leaves no hostile action against the Iranian nation unanswered and will give a firm and appropriate response to any unwise measure when the time is ripe,� Seyyed Abbas Mousavi said on Friday, hours after two US warplanes conducted dangerous maneuvering near Mahan Air�s Flight 1152.

Foreign Minister Mohammad Javad Zarif also condemned the �lawlessness� of the United States which �endangered� lives of civilians on board the Iranian airliner.
