Bomb blast kills 2 in Karachi

The bomb went off outside a car showroom in the southern residential district of the country's industrial and commercial hub.

"Two employees of the car dealer were killed and four others were injured," city police chief Fayaz Leghari told AFP.

The blast also damaged six vehicles and three shops.

Leghari said it was a time device and preliminary investigations indicated business rivalry could be the motive.

"The initial investigations suggest the incident was an outcome of business rivalry. We don't think it was an act of terrorism," he said.

"It was apparently meant to damage the showroom business."

Karachi has been hit by a series of bomb blasts in recent months including two suicide bombings at mosques in May that killed 48 people and injured about 150.
