Iran fights to keep gulf Persian

Users who type the words "Arabian Gulf" are in for a surprise

It is said to have withdrawn an invitation to National Geographic magazine to attend a festival because they refer to the Gulf as both.

Iranian bloggers also launched a web action on the Google search engine.

The words "Arabian Gulf" elicit a spoof message: "The Gulf you are looking for does not exist. Try Persian Gulf."

The practice, known as "Google bombing", has been used in the past against George W Bush, who comes up under "miserable failure".

The message parodies the text which usually appears when a web page does not exist, and goes on to recommend that users should read "some history books".

It is the second time Iranian bloggers have united to make a political point.

Earlier this year, they used their weblogs to direct users to pro-reformist websites and online newspapers that had been closed down by the Iranian authorities.

Al-Jazeera under fire

In Tehran, organisers of a photo festival told the AFP news agency they had invited National Geographic's picture editor, Susan Welchman, to join them on the jury for the exhibition's competition, but said she was now no longer welcome.

National Geographic has already been banned from going on sale in Iran, pending a "correction" of the atlas.

On Monday, Iran threatened the Arabic satellite TV al-Jazeera with action for an online animated cartoon published in the wake of the National Geographic ban.

It shows an Iranian cleric ignoring regional problems in favour of taking action over what to call the Gulf.
