Bomb kills two in Baluchistan
The blast happened in the remote town of Hub in Baluchistan province, near the Arabian Sea coast, police official Mohammad Siddique told AFP.
"The bomb attached to a timer was concealed in a shopping bag. Two people were killed and two were injured," he said.
No one claimed responsibility for the explosion but largely-desert Baluchistan has been gripped for more than two years by an insurgency led by autonomy-seeking tribal rebels, which has left hundreds dead.
The rebels, who mainly attack government installations, gas pipelines and electricity lines, want more political control and a greater share of the province's natural resources.
President Pervez Musharraf said on May 10 that most rebel camps had been "smashed" since the army killed rebel chief Nawab Akbar Bugti in August 2006, but reiterated an amnesty offer for tribesmen.
