The incident took place in Ali Lala area in eastern Ghazni city after explosives planted in a cycle went off on Sunday afternoon.
Provincial governor spokesman Sabawoon said the explosive device was planted by anti-government armed militant groups and all the victims of the last are Afghan civilians.
In the meantime provincial hospital chief Baaz Mohammad said at least two people including an Afghan man and kid who were injured following the blast were taken to the hospital.
No group including the Taliban militants have so far claimed responsibility behind the incident. Taliban militants and other anti-government armed groups frequently use improvised explosive device as the weapon of their choice to target Afghan and coalition forces which normally leads to civilians casualties.
Ali Lalai area is considered to be a busy place in eastern Ghazni city and there are fears of increase in casualties as a result of today’s blast.
