Afghan officials: Suicide bomber kills 6 in country's north

Afghan officials say at least six people have been killed in a suicide bombing in northern Parwan province.

Mohammad Sayed Seddiqi, administrative chief of Siagird district, says the bomber was on a motorbike when the attack took place Tuesday near a bazaar during the traditionally busy morning hours.

He says the bomber targeted the local police headquarters. Seddiqi also says at least one police officer was among 26 wounded.

Haroon Mubarez, a district police commander, says guards spotted the bomber and ordered him to stop before he was able to enter the police compound.

No group immediately claimed responsibility for the attack. The Taliban have stepped up their attacks on Afghan security forces over the past year as they intensify their 15-year fight to overthrow the Kabul government.
