Officials earlier had reported two bomb blasts targeting Afghan security forces in different parts of the country that killed at least eight.

The first explosion occurred in southern Afghanistan's Kandahar province when a suicide bomber on a motorcycle struck a police station in Kandahar City, killing three policemen, said Ahmad Javed Faisal, spokesman for the Kandahar Media and Information Center.

In the second incident, five Afghan National Army soldiers were killed when a bomb targeting a convoy was remotely detonated in eastern Laghman province's Bad Pakh district, Sarhadi Zwak, a spokesman for the provincial governor, said.
