"One blast was a vehicle IED (improvised explosive device)," Javed Faisal, spokesman for the Kandahar provincial governor, told AFP. "Seven people are dead and more than 50 are wounded, most of them civilians."
Faisal said that the target of the attack appeared to be police and army vehicles but that many of those injured were civilians who were gathered in a popular public area of the city at the end of the Friday holiday.
The Kandahar provincial media centre said many children were among the severely injured after the blasts at 1500 GMT.
