The Pakistani Taliban says it sent two suicide bombers to a paramilitary training academy on Friday, to avenge Osama bin Laden's death. It warns there will be more attacks.
''It's the first revenge for the martyrdom of ... bin Laden. There will be more,'' Taliban spokesman Ehsanullah Ehsan said by telephone from an undisclosed location.
Eighty people were killed and at least 120 were wounded by the bombs in the town of Shabqadar in northwest Pakistan.
Sixty-five of the dead were recruits at the academy. At least 120 people were wounded.
The BBC reports the bombings happened as newly trained cadets from the Frontier Constabulary were getting into buses after completing their course.
The Frontier Constabulary is used to police the regions bordering Pakistan's tribal areas.
Shabqadar is on the border with Afghanistan, about 35 kilometres north-west of Peshawar.
The al Qaeda leader was killed by US Special Forces in a raid in the northern town of Abbottabad.
