A bomb blast that appeared to be targeting a provincial government minister killed 11 people before dawn at a football field in southern Pakistan, the latest in a series of attacks that left 28 people dead across the country, officials said.
The bomb planted next to the field in the city of Karachi was hidden in a motorcycle, said senior police official Razaq Dharejo. The bomb went off near the vehicle of provincial minister Javed Naghori, who was leaving after witnessing a late-night match between local teams in the Lyari neighbourhood, said Mr Dharejo. Mr Naghori escaped unharmed.
The blast killed 11 people and wounded 24 others, said provincial Information Minister Sharjeel Memon. Many of the dead and wounded were young boys standing near the football field when the bomb exploded.
No one has claimed responsibility for the attack. Karachi is Pakistan's largest city and has a long history of political, criminal and religious violence.
On Tuesday, police found the bodies of 13 people who were pulled off a convoy of buses in southwest Baluchistan province, shot dead and dumped in a ravine, officials said. A paramilitary soldier was also killed.
The motive for the attack late on Monday night in Baluchistan province was unclear since no one claimed responsibility. But suspicion may fall on separatists who have been waging a low-level insurgency in southwest Baluchistan province.
The buses were headed to central Punjab province, and the separatists have a history of attacking Punjabis whom they view as outsiders encroaching on their independence. The province is also home to Islamic militants who have carried out past attacks, especially on minority Shiite Muslims.
Paramilitary troops protect bus convoys moving through Baluchistan. But gunmen distracted the troops by shooting at an oil tanker, said Kashif Nabi, a local government administrator.
Then, dozens of other gunmen dressed in tribal police uniforms stopped the convoy of five buses at a security checkpoint about four miles away after overpowering the nine policemen who were stationed there, said Abdul Waheed, deputy commissioner of Bolan district, where the attack took place. The attackers surrounded the buses, and two gunmen entered each vehicle to check the identities of passengers, said Mr Waheed. A paramilitary soldier trying to sneak into the area was killed by the gunmen.
The attackers took 22 passengers with them, including nine tribal policemen, Mr Waheed said, but they left the policemen a few miles away because they were locals, and continued on with the 13 hostages. Police found the bodies near the town of Machh, around six miles from the checkpoint where the buses were stopped, said Nabi, the local administrator who works in Machh.
