A bomb planted on a motorbike exploded in Pakistan`s restive southwestern province of Baluchistan Thursday, wounding at least 10 people, police and administration officials said.
The bomb went off in Sibi city, around 110 kilometres (68 miles) southeast of Quetta, capital of Baluchistan province, which is rife with sectarian militants and ethnic Baluch separatists.
"At least 10 people have been injured in the blast... in Sibi city," district police chief Anwar Khetran told AFP.
A senior government official in Quetta confirmed the incident and causalities.
"The bomb contained 2.5 kilogrammes (5.5 pounds) of explosives. At the moment, we are not aware of its target," Akbar Hussain Durrani, home secretary of Baluchistan province, told AFP.
No one immediately claimed responsibility for the attack.
Baluchistan, Pakistan`s largest but least developed and most sparsely populated province, is racked by Islamist militants, banditry and sectarian violence between Sunnis and Shiites.
In October the Human Rights Commission of Pakistan said that more than 300,000 people, including minority Shiites and Hindus, had left Baluchistan over the past 10 years due to rising unrest.
