Local officials said at least five people were killed and seven wounded in a suicide attack that targeted a meeting of tribal elders in a restive Pakistani tribal area.
The bombing took place in Pir Mela village of the Khyber tribal region, some 100 kilometers southwest of Peshawar on October 15.
The officials said a suicide bomber blew himself up killing and wounding tribesmen attending a meeting of tribal elders who oppose to Taliban militants.
There were no immediate claims of responsibility for the attack.
Khyber is located in Pakistan's semi-autonomous tribal belt near the Afghan border.
Militant groups linked to the Taliban and Al-Qaeda have a strong presence in the area and stage attacks both in Pakistan and Afghanistan.
Pakistani military jets have recently conducted air strikes targeting suspected insurgent hideouts in the area.
