At least four people have been killed and 22 wounded by a suicide bomber who attacked an army vehicle on the outskirts of Pakistan's southwestern city of Quetta.
Quetta police officer Abdur Razzaq Cheema said the army vehicle, transport for a colonel in Pakistan's armed forces, was parked near a bus terminal when the attack took place on November 25.
Cheema said the army colonel was not in the vehicle at the time of the attack.
Muhammad Khurasani, a spokesman for Tehrik-e Taliban Pakistan (TTP), claimed in an e-mail sent to the media that the Pakistani Taliban was responsible for the suicide bombing.
The authorities said all of those who died were civilians. They said four members of Pakistan's security forces were among those wounded.
Waseem Baig, a spokesman for Quetta's Civil Hospital, confirmed the death toll after the bodies of victims were brought there.
Explosives experts said the attacker used a suicide vest containing about 10 kilograms of explosives with steel balls as shrapnel.
