The blast hit a bus which was rented by the Afghan ministry of information and technology to transport employees, said Abdul Samad Hamid Poya, a ministry adviser.
He added that it was unclear at the moment who the victims are.
No one claimed immediate responsibility for the blast, but the Afghan government has blamed the Taliban for running an assassination campaign against government employees, civil society figures and journalists.
