The militant was identified by the NDS operatives and shot dead before he carry out the attack, the provincial government media office said, adding that another militant managed to flee the area.
The anti-government armed militant groups have not commented regarding the incident so far.
Taliban militants and insurgents belonging to the other militant groups are actively operating in Kandahar province despite the security situation has improved during the recent months.
The militants are attempting to destabilize the province as they try to expand their insurgency activities across the country, specifically since they launched their spring offensive in April this year.
In the meantime, the Afghan security officials are saying that the spring offesive led by the Taliban group has been succesfully repulsed with the launch of the annual counter-terrrism operations.
