In claiming responsibility, the al-Qaida linked militant group cited anger at Pakistan's military for failing to stop the American incursion on their soil.
The blasts in the northwest were a reminder of the savagery of Islamist insurgents in Pakistan. Tensions also have risen between the U.S. and Islamabad over allegations that some elements of Pakistani security forces had been harboring bin Laden, who died in a May 2 raid in Abbottabad, a garrison town about three hours' drive from the scene of the bombing.
"We have done this to avenge the Abbottabad incident," Ahsanullah Ahsan, a spokesman for the Pakistani Taliban, told The Associated Press in a phone call. He warned that the group was also planning attacks on Americans living inside Pakistan.
The bombers blew themselves up in Shabqadar at the main gate of the facility for the Frontier Constabulary, a poorly equipped but front-line force in the battle against al-Qaida and allied Islamist groups like the Pakistani Taliban close to the Afghan border. Like other branches of Pakistan's security forces, it has received U.S. funding to try to sharpen its skills.
At least 80 people were killed, including 66 recruits, and around 120 people were wounded, said police officer Liaqat Ali Khan.
