People familiar with Iran’s Supreme Leader health situation say Ali Khamenei is gravely ill and is currently on bed rest under observation by a team of doctors, the New York Times reported. 

The newspaper on Friday quoted four people familiar with Khamenei’s health condition as saying that all his meetings are cancelled while there have been numerous rumors about his death on social media in recent days. 

Iran International had earlier reported about Khamenei absence from the public scene since the beginning of this month, while some pundits said separately that Khamenei has given Raisi authority to make decision over Iran’s nuclear talks with the West.

The octogenarian leader had surgery at a clinic set up at his home and office complex some time last week for bowel obstruction after suffering extreme stomach pains and high fever, one of the people said. 

One of the sources said he is currently being monitored around the clock by a team of doctors, claiming that his condition was critical last week, but has improved, and he is currently resting. 

The Iranian government has not denied social media reports circulating for more than a week about Khamenei's illness. Meanwhile, his office cancelled two scheduled meetings with the Assembly of Experts members and Basij militia during the past days.

In another development, a picture released by the official news agency IRNA last week about Khamenei's meeting with athletes, turned out to be at last three years old and the agency pulled the story.
