ISLAMABAD, Pakistan (CNN) -- A suicide blast in Pakistan's violence-plagued tribal region killed 11 people Thursday, police said.
The explosion took place at a restaurant in the town of Jandola, said Mohammad Riaz of the town's police. The suicide bomber walked in and blew himself up, police said.
Seven additional people were wounded in the explosion, which targeted members of the pro-government Turkistan tribe who were inside the restaurant, according to authorities.
The attack is most likely part of the ongoing fighting between militants loyal to Taliban leader Baitullah Mehsud and members of the Turkistan tribe, police said.
On Wednesday, a suspected U.S. missile strike killed seven people in the tribal region.
The strike happened in the evening near the village of Makeen in south Waziristan, according to the sources who requested anonymity because they are not authorized to speak to the media.
The area is a known stronghold of militant Mehsud.
