The Taliban claimed responsibility for the bomb blast outside the police headquarters in Kandahar, Reuters reported.
Yousuf Stanizai, a spokesman for the Afghan Interior Ministry, said there were 14 dead and 12 wounded. Seven of those killed were police officers, and the others were civilians, he said.
Some of the wounded were in critical condition.
