Islamabad, Pakistan (CNN) -- Two explosions targeting a government building in Pakistan's tribal region Monday killed 35 people and injured at least 70 others, officials said.
The blasts occurred as government officials were about to meet with members of a volunteer militia group established to fight militants in the area, said Maqsood Amin, a senior government official in Mohmand Agency.
Amin said two suicide bombers were responsible for the blasts. One detonated inside the building and another outside the building's gate, he said.
The explosions occurred in the agency's headquarters of Ghalanai, Pakistan.
The 35 dead and 70 injured were brought to Ghanazai hospital there after the blast, said Mohammad Zafar, a senior medical officer there.
Mohmand is one of seven semi-autonomous tribal agencies along the 1,500-mile border that Pakistan shares with Afghanistan.
The Pakistani military has been battling insurgents in the area for some time. CNN
