A bomb blast in an Afghan market today killed two people, authorities said, also reporting other unrest-linked violence that left three more civilians and 14 militants dead.
The bomb, attached to a vehicle, exploded in a vegetable market in the eastern city of Khost, provincial intelligence chief Colonel Mohammed Yaqob told AFP.
A 15-year-old boy and a man were killed and 15 other people wounded, Yaqob said. There was no claim of responsibility.
Khost, which borders Pakistan, sees regular attacks most often linked to an insurgency led by the hardline Taliban, who were driven from government in a US-led invasion in 2001.
Taliban insurgents meanwhile said they had killed a district governor in another border province, Kunar, whose bullet-riddled body was found today.
The governor of Marawara district, Ghais Haqmal, had been abducted by Taliban three months ago and the militants had demanded the release of 50 of their jailed comrades in exchange for his life, authorities said.
The demand could not be met, "so they killed the district governor and today is his funeral," Kunar government spokesman Adris Gharwal told AFP.
Another Afghan man was shot dead by Taliban in the central province of Ghazni after being accused of spying for the government and its allies in the international military, a provincial government spokesman said.
The US-led military supporting the Afghan government announced meanwhile that troops had killed 14 insurgents in operations in the southern provinces of Helmand and Farah in the past two days.
