Provincial governor’s spokesman Nematullah Temori confirmed that the Taliban militants have launched a coordinated attack in Dashti Archi district.
Temori further added that heavy clashes are still underway between the militants and armed forces but did not disclose further information regarding the casualties.
Unconfirmed reports indicate at least thirty soldiers lost their lives in the attack and at least 17 others sustained injuries.
However, another official, speaking on the condition of anonymity, said at least sixty soldiers have been killed or wounded in the attack.
The source further added that the attack was carried out by the militants belonging to the red unit of the Taliban group.
According to the official, the attack was carried out on security posts between Dashti Archi of Kunduz and Khwajah Ghar of Takhar province.
The security and defense authorities have not commented regarding the casualties of the armed forces so far.
Kunduz is among the relatively volatile provinces in North of Afghanistan but the security of the province has sharply deteriorated during the recent years amid ongoing efforts by the militants to expand their insurgency in key northern provinces.
