PESHAWAR - Two explosions went off minutes apart in the northwest Pakistani city of Peshawar, killing 34 people and injuring more than 100 in one of the deadliest attacks since the US raid that killed Osama bin Laden last month, officials said.

The blasts, one of which was caused by a suicide bomber, occurred just after midnight Sunday in an area of the city that is home to political offices and army housing.

The attack took place as CIA Director Leon Panetta and Afghan President Hamid Karzai visited Islamabad, 95 miles (150 kilometers) to the east, to speak separately with senior Pakistani officials about intelligence sharing and efforts to reconcile with the Taliban.

The first explosion was relatively small and drew police and rescue workers to the site, said Dost Mohammed, a senior local police official. A large explosion rocked the area a few minutes later, causing the fatalities and wounding 108 people, 18 critically, said Rahim Jan, a senior doctor at a local hospital.

The second blast was caused by a suicide bomber riding a motorcycle packed with 22 pounds (10 kilograms) of explosives, said Ejaz Khan, a senior police official. The source of the first explosion was unknown.

No group claimed responsibility, but the Pakistani Taliban have pledged to carry out attacks in retaliation for the covert US Navy SEAL raid that killed bin Laden in an army town outside Islamabad on May 2.

Sundays' attack took place across the street from the offices of the top political agent to Khyber, part of Pakistan's volatile tribal region, and only about 100 yards from army housing units. Peshawar borders the tribal region and has been repeatedly hit by bombings over the past few years.

The dead included at least one journalist, said Mohammed Farooq, a hospital doctor. Another four journalists and at least 10 police were injured, he said. Many of the people killed were so badly burned they were difficult to identify.

Jamal Khan, a 22-year-old student, was in his apartment when the first blast went off. He rushed to the scene as the second explosion occurred, peppering his face and arms with flying debris.

"The explosion was so huge I will never forget it all my life," said Khan as he recovered in a hospital. "It was deafening, and then there was a cloud of dust and smoke. When the dust settled, I saw people crying for help and body parts scattered everywhere."

The bombings followed a second day of meetings between Panetta, the CIA chief, and senior Pakistani officials. The talks were slated to focus on the size and scope of US intelligence activities in the wake of the raid that killed bin Laden, said a Pakistani official, speaking on condition of anonymity because of the sensitivity of the issue.

The bin Laden operation plunged an already strained relationship between the CIA and Pakistan's main intelligence agency, the ISI, to new lows and threatened cooperation that is key to the US fight against al-Qaida and Taliban militants battling foreign troops in Afghanistan.

The US also needs Pakistan's help to promote and guide negotiations with the Taliban that can help end the decade-long Afghan war. Pakistan and Afghanistan inaugurated a joint peace commission Saturday during a visit by Karzai, the Afghan president.

In an attempt to rebuild their relationship, Washington and Islamabad have agreed to form a joint intelligence team to track down militant targets inside Pakistan, drawing in part from the trove of records taken from bin Laden's personal office during the raid.
