A bomb ripped through a Pakistani bus in Karachi on Thursday, killing four naval personnel and a passing motorcyclist in the third attack on navy transport this week in the country's biggest city. A dozen people were wounded in the attack claimed by the Taliban in Pakistan's politically tense economic capital and southern port, where NATO ships supplies to the 130,000 US-led troops fighting in Afghanistan. Two other navy buses were bombed on Tuesday, dealing a blow to the military just days after Pakistan's army chief General Ashfaq Kayani claimed his forces had "broken the back" of Taliban and Al-Qaeda-linked militants. "Now a total of four of our employees -- all sailors -- have been martyred in the attack on our bus, while seven others are injured," spokesman Commander Salman Ali told AFP. Four other navy personnel died on Tuesday.
The navy said the bomb was planted in a manhole. The explosives tore through sign boards, a fuel station and parked cars, and rescue workers were afterwards seen covering bodies with white sheets.
