Twin suicide bombings at a paramilitary base in northwestern Pakistan killed as many as 80 people Friday. At least 66 of the bombing victims were recruits at the training center, the BBC reports.
It occurred at the training center in Shabqadar, Charsadda district. Shabqadar lies on the border with Afghanistan and is about 22 miles north-west of Peshawar.
This was the bloodiest attack in Pakistan since U.S. forces killed Osama bin Laden on May 2.
It comes as a reminder of the high price Pakistanis pay for the terrorist and militant groups operating within its borders.
A suicide bomber detonated one of the blasts at the facility's front gate. It was not known how the second bomb went off.
"There was a big blast," a vegetable vendor told AP. "I saw smoke, blood and body pieces all around."
Security forces fighting the Taliban and other militants in the northwest of the country have been the target of similar attacks, but this is the deadliest attack this year, BBC reports.
No group has claimed responsibility for the blast. However, militant groups have vowed to avenge the killing of Al Qaeda leader bin Laden.
