The attack occurred on the grounds of the main government compound in Mohmand, part of Pakistan's militant-infested tribal region. It was the latest strike against local tribesmen who have been encouraged by the government to take up arms against the Taliban.
The explosions also wounded more than 100 people, many of them critically, said Mian Iftikhar Hussain, information minister of neighboring Khyber Pakhtunkhwa province.
One of the reasons the attacks were so deadly was because the bombers had filled their suicide jackets with bullets, said Amjad Ali Khan, the top political official in Mohmand, who was at the compound in Ghalanai town when it was attacked.
"These bullets killed everyone who was hit," said Khan.
Both of the bombers were disguised in tribal police uniforms, said Khan. One of them was caught at the gate of the compound, but he was able to detonate his explosives, he said.
One of the wounded in the attack was 45-year-old Qalandar Khan, who came to the compound to visit an imprisoned cousin and was hit by the second explosion.
"There was a deafening sound and it caused a cloud of dust and smoke and a subsequent hue and cry," said Khan, laying in a hospital bed in his blood-soaked clothes. "There were dozens on the ground like me, bleeding and crying. I saw body parts scattered in the compound."
The dead and wounded included tribal elders, police, political officials and other civilians. Two of the dead were local TV journalists who were at the compound reporting on stories, said Shakirullah Jan, president of the Mohmand press club.
The Pakistani army has carried out operations in Mohmand to battle Taliban and al-Qaida fighters in the area, but it has been unable to defeat the militants.
The military has encouraged local tribesmen to form militias to oppose the militants. These groups have had varying degrees of success and have often been targeted in deadly attacks.
A suicide bomber attacked a mosque in northwestern Pakistan in early November that was frequented by elders opposed to the Pakistani Taliban, killing 67 people. The attack occurred in the town of Darra Adam Khel, a militant stronghold on the edge of the tribal region.
"We are not scared of such attacks and will keep on taking these enemies of humanity to task until they disappear from society," said Hussain, the information minister.
