New allegations against Iran are heightening fears the Bush administration is planning a second war in the Persian Gulf. This weekend, administration and military officials accused the Iranian government of sending sophisticated roadside bombs to Iraq that have killed 170 coalition troops in the last three years. Military officials formally unveiled the charges at an unusual news conference in Baghdad. The officials refused to be quoted by name and barred all recording devices from the room. Reporters were shown images of weapons with serial numbers the Pentagon says originate in Iran.

The Iranian government is denying the accusations. On Monday, President Mahmoud Ahmadinejad was asked by ABC's Diane Sawyer whether Iran is sending weapons into Iraq to kill Americans.

Meanwhile, the top US military commander, General Peter Pace, added to growing doubts about the accusations Monday when he admitted he could not endorse them.

• Gen. Peter Pace: "Gen. Peter Pace: "We know that the explosively formed projectiles are manufactured in Iran. What I would not say is that the Iranian government, per se, knows about this. It is clear that Iranians are involved, and it's clear that materials from Iran are involved, but I would not say by what I know that the Iranian government clearly knows or is complicit."

General Peter Pace, speaking in Australia. The Bush administration is insisting the new allegations do not signify a build-up towards war. In an interview with C-Span Monday, President Bush defended the White House pressure on Iran and mocked speculation of a possible US attack.

• President Bush: “I guess my reaction to all the noise about, you know, ‘He wants to go to war’ is, first of all, I don’t understand the tactics, and I guess I would say it’s political."

Amid these new developments, a new article in Vanity Fair magazine says the behind-the-scenes maneuvering that led to the Iraq war is being repeated today. The article says: “Once again, neocon ideologues have been flogging questionable intelligence about W.M.D. Once again, dubious Middle East exile groups are making the rounds in Washington—this time urging regime change in Syria and Iran. Once again, heroic new exile leaders are promising freedom."
