Iranian supreme leader Ayatollah Ali Khamenei has undergone a successful prostate surgery in Tehran.

Alireza Marandi, the physician who treated the leader, said Khamenei underwent the surgery without anaesthetics and he is in normal condition following the surgical procedure.

"I have a surgery and I am now leaving for the hospital. There is no reason to worry; this, of course, does not mean that I don't need people's prayers, but God willing, there is no point to worry as it is a normal operation. God willing everything will go on well," Khamenei told a state-run news agency prior to his surgery.

The 75-year-old leader has the final say in all Iranian affairs and wields the highest political authority.

Khamenei was Iranian president for eight years before becoming the supreme leader of the country in 1989.
