A homemade bomb exploded outside a crowded roadside restaurant in a southwestern Pakistan city on Sunday, wounding 14 people, police said.
The explosion occurred in downtown Quetta, the capital of Baluchistan province, near a restaurant filled with people buying breakfast, said police officer Niaz Mohammed.
Mohammed initially said four men were wounded after being hit by pieces of shattered glass and splinters from the bomb. But a police investigator, Mohammed Maqbool, said 14 people had been injured, including five children standing nearby and a woman who was passing by when the explosion occurred.
One man was listed in a serious condition at the state-run Civil Hospital, Maqbool said.
Mohammed blamed rebel tribesmen for the attack but did not offer any evidence to back up his claim.
Baluch rebels are waging an often violent campaign for a greater share of the wealth obtained from natural resources, including gas and oil, extracted in their province.
Tension has been high in Baluchistan since the August 26 killing of Nawab Akbar Bugti, a prominent ethnic-Baluch tribal chieftain who was accused by authorities of leading violent attacks against the local government.
Authorities said Bugti died when the cave in which he was hiding collapsed in an unexplained explosion during a search by security officials for militants in the region.
On Friday, at least five people were killed in another bomb explosion in the Baluchistan town of Barkhan which police blamed on supporters of Bugti.
Bugti's supporters have staged rallies and strikes following his death. Several people have died and dozens have been injured in the protests.
