Iran's President Mahmoud Ahmadinejad -- whose nation may well be aspiring to a nuclear weapons program -- isn't backing down from his call for Israel to be "wiped off the map."

Some excerpts from the BBC story:

Tens of thousands of Iranians took part in the rally in Tehran which Iran organises every year on the last Friday of the fasting month of Ramadan to show solidarity with the Palestinian struggle.

Shouting "Death to Israel, death to the Zionists", the protesters dragged Israeli flags along the ground and then set them on fire.

Many carried posters and placards sporting the slogan "Israel should be wiped off the map".

Joining the protest, Mr Ahmadinejad said: "My words were the Iranian nation's words.

"Westerners are free to comment, but their reactions are invalid," Mr Ahmadinejad told the official Irna news agency.

But while most Muslim and Arab capitals have remained silent on the remarks, a few have spoken out - including Palestinian chief negotiator Saeb Erekat.

"Palestinians recognise the right of the state of Israel to exist and I reject his comments," he told the BBC News website.

"What we need to be talking about is adding the state of Palestine to the map and not wiping Israel from the map," he said.

UN Secretary General Kofi Annan has issued a rebuke of Iran, and Israel called for Iran to be expelled from the UN.
