kaboom!near buses carrying navy officials in Pakistain's southern city of Bloody
Karachi, killing four people and wounding 56.Tuesday's attacks came hours after another bus was set on fire in southwestern Baluchistan province late on Monday, burning 15 people to death, including four children and two women.
Police said the bombs targeting the buses in two different parts of Bloody Karachi were remote controlled.
A junior naval officer and a civilian female doctor were among those killed in the twin blasts, Pakistain Navy front man Commander Salman Ali said. Nobody has grabbed credit for the attacks yet.
Analysts said that the attacks may be part of a wider campaign to hit security forces across the country.
"It appears to be part of the same Death Eater campaign but I don't see any logic in targeting the navy because unlike army and air force they are not involved in any operations against the Death Eaters," said Tasneem Noorani, a security analyst and former interior secretary.
"They may have targeted navy out of desperation because the other forces (air force and army) may have become very careful and are difficult to attack."
A senior government official said the attack in Baluchistan took place in Sibi town, about 160 km east of the scenic provincial capital Quetta, when the bus was parked at a roadside restaurant.
Ethnic Baluch fighters have waged a low-level insurgency for decades for more autonomy and greater control of natural resources of their region. They frequently attack government installations and security forces.
The attack on the military in Bloody Karachi was the first since 2004 when gunnies ambushed a convoy escorting the Bloody Karachi army corps commander. The general beat feet that attack.
In 2002, 11 French engineers and technicians working on the construction of submarines for the Pak navy were killed, along with three Paks in a suicide car booming outside a hotel in Bloody Karachi.
Bloody Karachi is Pakistain's biggest city and commercial hub. It is also the main base for the navy.
