At least six people, including three paramilitary forces personnel and two policemen were killed and another 46 were injured in a suicide attack on the convoy of the Balochistan inspector general police in Quetta late on Sunday night.
A police official said the suicide bomber rammed his explosives-laden vehicle into the convoy of IG Police Mushtaq Sukhera.
He said the IG narrowly escaped the attack which shattered the windows of nearby homes.
When contacted, Balochistan Home Secretary Akbar Hussain Durrani told Pakistan Today that the explosives weighed 1,000 kilogrammes. He said the IG had just reached the residence when the blast occurred, adding that three personnel of Frontier Corps and two policemen were among the dead.
At the time of the blast, the activists of the Balochistan National Party were also passing by.
After the blast, the electricity supply was disrupted due to damages to power pylons.
No group has claimed the responsibility for the blast until the filing this report. However, hospital sources said the death toll might escalate as some of the injured were in serious condition.
The blast was followed by six rocket attacks on Quetta city. Police said militants fired six rockets from an undisclosed location. Rocket attacks caused panic among the local populace.
