In a statement on Thursday, Mousavi said Iran will take necessary political and legal actions once the investigation is completed.
“Meanwhile, Iran’s permanent representative and ambassador to the United Nations Majid Takht-Ravanchi has explicitly emphasized to UN Secretary General Antontio Guterres that Iran will hold the US responsible if anything happens to this airplane in its way back,” Mousavi added.
The message has also been conveyed to the Swiss ambassador to Tehran, whose country protects the US interests in Iran, he noted.
Two US fighter jets came close to a Mahan Air passenger plane in Syrian airspace, causing the pilot to quickly change altitude to avoid collision.
A video posted by Iran’s IRIB news agency showed a jet from the window of a plane and blood on the face of a passenger – reportedly as a result from an injury sustained during the sudden altitude change.
IRIB initially reported a single Israeli jet had come near the plane but later quoted the pilot as saying there were two jets which identified themselves as American.
The pilot of the passenger plane contacted the jet pilots to warn them about keeping a safe distance and the jet pilots identified themselves as American, IRIB reported.
The plane later landed in Beirut, safely evacuating its passengers, some of whom were injured.
It immediately took off and returned to Tehran’s Imam Khomeini Airport without any harassment, media reports say.
