Inspector General Mushtaq Sukhera had just entered his residence in Quetta when a suicide bomber in a vehicle laden with explosives blew themselves up outside.
"At least two policemen, three paramilitary soldiers and one passerby were killed outside the inspector general's residence and 46 others were wounded," Home Secretary Akbar Durrani told AFP.
A huge amount of explosives were packed into the vehicle and the blast left a deep crater, with the explosion shattering nearby windows and sending debris flying, he said.
Senior police official Mobin Ahmed told AFP the police chief was safe, while another police official said the blast was so loud it was heard all over the city.
