The attacker blew himself up at meeting on Wednesday in Pir Mela village, 100km southwest of Peshawar, in the Tirah Valley of the Khyber tribal region, officials told the AP and AFP news agencies.

A local official referred to the gathering as a "peace meeting".

The AFP that the wounded were taken to a government hospital. The Pakistani newspaper Dawn said the victims were yet to be identified.
