Mohammad Khatami

Iranian President Mohammad Khatami has marked the 26th anniversary of the Islamic revolution with a stern warning that any invaders will face what he calls a "burning hell."

Addressing tens of thousands of Iranians Thursday in central Tehran, Mr. Khatami said the Islamic republic does not seek "war, violence or confrontation."

Iran is facing mounting international pressure over its nuclear program, which the United States alleges is aimed at developing nuclear weapons. President Bush says he has not ruled out the use of military force, if negotiations fail to end the threat.

Today, for a second time in two days, Mr. Khatami dismissed Mr. Bush's comments as part of a psychological war.

Britain, France and Germany are engaged in ongoing talks with Iran aimed at persuading Tehran to end its nuclear enrichment program. Negotiators in Geneva have reported little progress in the talks.
