Kabul - An army general and four civilians have been killed by the Taliban in northern and north-eastern Afghanistan in two separate incidents, officials said on Monday.

General Attaullah Attaye was killed in an insurgent ambush in Kunduz early Monday, a military spokesman said, adding that another officer had been wounded in the incident.

Attaye had been travelling from Takhar to Baghlan when his vehicle came under attack from insurgent in the Chaartoot area of Kunduz province, the spokesman said.

Separately, Taliban insurgents shot dead three women and a child in Sayaad district, Sar-e-Pul provincial police chief Khalilullah Dastyar told dpa, adding that the reason for the killing was unclear.

The Taliban denied involvement in the incident.

In early January, four police were killed in a Taliban ambush in the north-eastern Badakhshan province.
