A powerful bomb went off outside the home of a provincial minister at Quetta in southwest Pakistan on Thursday, killing at least three people and injuring as many others.
The bomb is believed to have been planted in an SUV parked at the residence of Balochistan Finance Minister Mir Asim Kurd Giloo in the posh Railway Housing Society. The minister was not at home when the explosive device went off, police said.
Three persons - an employee and a security guard of the minister and the driver of a tractor-tanker that was delivering water to the house - were killed by the explosion, they said.
Witnesses said their body parts were strewn all over the blast site.
The condition of two of the three injured was described by hospital officials as serious.
Giloo, who was at the provincial secretariat, rushed back to his home but police barred him from going inside. The minister and his family were taken away to an undisclosed location by police.
Police officials said it was yet to be determined how the bomb was planted in the vehicle.
The blast blew out the windows of nearby buildings and triggered a minor fire at the minister's home that was controlled by the fire brigade.
No group claimed responsibility for the blast.
Police cordoned off the area and launched a search operation.
Several ministers, bureaucrats and political leaders have their homes in the Railway Housing Society.
Quetta has witnessed an upsurge in violence, including bomb blasts and suicide attacks, in the past few days.
Nearly 70 people were killed when a suicide bomber targeted a rally organised by Shia students in the city last week.
