CAIRO, Egypt —  An Al Qaeda front group warned U.S. President George W. Bush Saturday that the Iraq war funding recently approved by Congress would not improve chances for success in the country.

After weeks of debate, the U.S. Congress passed the spending bill on Thursday, providing $95 billion for the wars in Iraq and Afghanistan.

"Don't be happy for the money allocated to your soldiers," said a statement issued by the Islamic State of Iraq. "With God's help, the money will heal no wound and change nothing at all ... the battleground will be a witness to what we say." The statement was posted on a Web site commonly used by Islamic extremists, but its authenticity could not be verified.

Bush acknowledged Thursday that Al Qaeda terrorists would likely intensify their attacks in anticipation of a September progress report by the top U.S. commander in Iraq.

"And so, yes, it could be a bloody — it could be a very difficult August," said Bush at a news conference.

Responding to these comments, the Islamic State of Iraq's statement said, "The tyrant of this era, Bush, came out to say that the coming days will be difficult on the Rafidain (Iraq) land, but we tell him that they will be tougher for the enemy than the old days."

The statement also reminded Bush of comments made in late January by Al Qaeda's second-in-command, Ayman al-Zawahri, mocking the president's plans to send more than 20,000 additional troops to Iraq to improve security.

"Why not send 50 or 100 thousand?" said al-Zawahri in a videotape. "Aren't you aware that the dogs of Iraq are pining for your troops' dead bodies ... so send your entire army to be annihilated at the hands of the mujahideen to free the world from your evil."
