Ahmadinejad was born with a jewish surname

The document reveals that Mahmoud Ahmadinejad was previously known as Sabourjian – a jewish name meaning "cloth weaver".
The Sabourjians traditionally originate from Aradan , Mr Ahmadinejad’s birthplace, the name for the Jewish Tallit shawl in Persia. The name is even on the list of reserved names for Iranian Jews compiled by Iran’s Minister of the Interior.
“jian” ending to the name specifically showed the family had been Jews.
Mehdi Khazali, an internet blogger, is the son of Aytollah Khazali, a former member of the Guardian Council, who called for an investigation of Mr Ahmadinejad’s roots was arrested this summer.
Mehdi Khazali claimed that Ahmadinejad’s family name was changed from Sabourjian and his forefathers were Jewish converts into Islam.
Mr Ahmadinejad has regularly levelled harsh criticism at Israel, questioned its right to exist and denied the Holocaust. British diplomats walked out of a UN meeting last month after the Iranian president denounced Israeli’s 'genocide, barbarism and racism'.
In my opinion, that is an unverified gossip and it could be wrong.
