Reports from Iranian media suggest that Massoud Rajavi, the former leader of the group Mojahedin-e Khalq (MEK), which Iran designates as a "terrorist" organization, may have actually passed away three years ago due to health issues while under the supervision of the United States.

Born in 1948, Rajavi is believed to have succumbed to a heart attack after enduring several years of illness. These claims have been made in a report by the state-linked Tasnim news website, citing an unnamed security official and were made public on Sunday.

It is worth noting that neither the MEK, an organization advocating for the overthrow of the Iranian establishment, nor the U.S. government, has officially confirmed Rajavi's reported demise. In the public eye, Maryam Rajavi, his wife, has assumed the role of spokesperson for the MEK for the past two decades.

Massoud Rajavi has remained absent from public view since the United States' invasion of Iraq in 2003, leading to various speculations over the years. These speculations ranged from theories suggesting he had been killed long ago to the possibility of his imprisonment outside of Iran.
