The incident took place on Tuesday evening after a suicide bomber targeted a gathering of people in a Buzkashki competition, local officials said.
Provincial police chief, Gen. Ghulam Mustafa Mohseni confirmed at least five people were killed and nearly 20 others were injured following the explosion.
Gen. Mohseni further added that a former Mujahideen leader was the main target of the suicide bomber but he survived the attack.
He said a local security official was also among those injured in today’s suicide attack.
Kunduz is among the relatively peaceful provinces in northern Afghanistan where fewer security related incidents have been reported during the recent months.
The attack in Kunduz province comes as militants launched coordinated attacks in capital Kabul and eastern Kunar province of Afghanistan which left dozens killed or injured.
