WASHINGTON — The massive cache of computer files taken from Osama bin Laden’s compound contained a considerable quantity of pornographic videos, U.S. officials said Friday, adding a discordant note to the public image of the Islamist militant who long denounced the West for its lax sexual mores.

The officials, speaking on the condition of anonymity about classified material, would not say whether there was evidence that bin Laden or the other men living in the house had acquired or viewed the material.

In Charsadda, Pakistan, on Friday, suicide bombers killed 80 people at a Pakistani paramilitary academy in revenge for bin Laden’s death and militants in Pakistan vowed to carry out more attacks.

Additional fallout from that raid was felt in the Pakistani parliament, where Lt. Gen. Ahmad Shuja Pasha, Pakistan’s spy chief, said he was “ready to resign” over the bin Laden affair that has embarrassed the nation.

Pakistan’s opposition leader accused the Inter-Services Intelligence, or ISI, spy agency of negligence and incompetence.

The discovery of the pornography, first reported by Reuters, may not be surprising in a collection of five computers, 10 hard drives, and dozens of thumb drives and CDs whose age and past ownership is not known.

Three other U.S. officials familiar with evidence gathered during investigations of other Islamic militants said the discovery of pornography is not uncommon in such cases.

But the disclosure could fuel accusations of hypocrisy against the founder of al-Qaeda, who was 54 and lived with three wives at the time of his death, and will be welcomed by counterterrorism officials because it could tarnish his legacy and erode the appeal of his brand of religious extremism.

In a 2002 “letter to the American people,” bin Laden denounced U.S. culture for its exploitation of women’s bodies in dress, advertising, and popular culture.

A team of intelligence analysts under the CIA’s direction has been working to review the material seized from bin Laden’s house in Abbottabad, Pakistan, by the Navy SEAL team that killed him.

Officials have said the material shows that bin Laden was making notes about new ways to attack the United States and sending instructions by courier to subordinates and al-Qaeda affiliates.

Asked about the contents in an interview with Bloomberg Television, Attorney General Eric H. Holder, Jr., said, “I’m not sure we have any plot” that the intelligence review had found.

“On the other hand, he did seem to have a goal around the 10th anniversary of Sept. 11,” Mr. Holder said. “Certainly, he wanted to harm and was in the advanced operational stage of pulling the levers in the al-Qaeda organization.”

Jay Carney, the White House spokesman, confirmed that U.S. interrogators had questioned bin Laden’s three wives for the first time Thursday, 10 days after they were taken from the compound by Pakistani security forces. He declined to give more details, saying, “I can’t characterize the interaction.”

The three widows, Khairiah Sabar, Siham Sabar, and Amal Ahmed Abdulfattah, who is also known as Amal Ahmed al-Sadah, had been held and questioned for days by Pakistani officials before the CIA interrogators spoke to them.

Ms. Abdulfattah, who is Yemeni, was shot in the leg during the assault on bin Laden’s compound by Navy SEAL commandos.

Pakistan said it would repatriate the three widows and their children. One is from Yemen and the others from Saudi Arabia.

The Pakistani Taliban said Friday’s attack by two suicide bombers in the town of Charsadda was their first taste of vengeance.

“There will be more,” militant spokesman Ehsanullah Ehsan said by telephone from an undisclosed location.

The bombers struck as recruits were going on leave and 65 of them were among the 80 dead.U.S. State Department spokesman Mark Toner condemned the attack, offered condolences to the families of the victims, and stressed the U.S. alliance with Pakistan.

“Terrorists have shown time and again that they are the true enemy ... of the people and the government of Pakistan,” Mr. Toner said. “We respect the nation’s sacrifices in the fight against terrorism and will continue to stand with Pakistan in our joint struggle to disrupt, dismantle, and defeat al-Qaeda and allied terrorist organizations.”

Hours after the bombing, a U.S. drone aircraft fired missiles at a vehicle in North Waziristan on the Afghan border, killing five militants, Pakistani security officials said.

It was the fourth drone attack since bin Laden was killed, inflaming another sore issue between Pakistan and the United States. Pakistan officially objects to the attacks, saying they violate its sovereignty and feed public anger.

Military and intelligence chiefs gave parliament a closed-door briefing in which ISI’s General Pasha told legislators he was ready to take responsibility for any criminal failing, Information Minister Firdous Ashiq Awan said.

“If any of our responsibility is determined and any gap identified, that our negligence was criminal negligence, and there was an intentional failure, then we are ready to face any consequences,” Mr. Awan told Express TV, citing General Pasha.

Another member of parliament said General Pasha said he did not want to “hang around” if parliament deems him responsible. “I am ready to resign,” Riaz Fatyana quoted the ISI chief as saying.

The spy chief also told parliament bin Laden had been isolated, Mr. Awan said. “We had already killed all his allies and so we had killed him even before he was dead. He was living like a dead man,” Mr. Awan quoted General Pasha as saying.

The chairman of Pakistan’s joint chiefs of staff committee, General Khalid Shameem Wynne, canceled a five-day visit to the United States that had been set to begin on May 22.

“The visit could not be undertaken under existing circumstances,” a military official told Reuters.

The White House said President Obama would lay out his vision for Middle East policy Thursday, using bin Laden’s death as a chance to recast the U.S. response to political upheaval in the Arab world.
