A suicide bomber attacked a convoy carrying the top official in south-west Pakistan, injuring six people, police said today.
A security official said Baluchistan Chief Minister Nawab Muhammad Aslam Khan Raisani was not harmed in the attack in the provincial capital, Quetta.
The official, Abid Hussain, said five of those wounded in the attack were policemen whose vehicle was hit by the bomber. The blast also injured one pedestrian.
Mr Raisani was travelling in a separate vehicle.
No group has yet claimed responsibility for the attack.
Baluchistan has been wracked by a decades-long nationalist insurgency which has demanded more autonomy and a greater share of the province's natural resource wealth.
