CAIRO  Just as President Obama arrived in the Middle East, the television channel Al Jazeera broadcast an audiotape on Wednesday that it said was from Osama bin Laden, accusing Mr. Obama of planting new seeds of “hatred and vengeance toward Americans.”

The message focused on Mr. Obama’s decision to step up pressure on extremists in Pakistan. The speaker specifically blamed the president for the Pakistani military’s drive to retake an area in the Swat Valley that had recently come under the control of Taliban forces.

The speaker also blamed Mr. Obama for the “one million Muslims” who had to flee their homes because of the fighting. United Nations and Pakistani officials estimate that as many as three million people have been displaced by the conflict.

“Obama has followed the footsteps of his predecessor in increasing animosity toward Muslims and increasing enemy fighters and establishing long-term wars,” the recording said. “So the American people should get ready to reap the fruits of what the leaders of the White House have planted throughout the coming years and decades.”
