Officials in Afghanistan say two roadside bombings have killed eight civilians in southern Kandahar province.

Six more people were wounded in the blasts near the town of Spin Boldak.

Wednesday, Afghan officials said at least seven people were killed when security forces raided a Kabul hideout housing militants involved in an attack on President Hamid Karzai.

Afghan intelligence chief Amrullah Saleh said at least one of the dead militants directly participated in Sunday's attack on the president during a military parade in Kabul. Mr. Karzai escaped unharmed.

The intelligence chief also said there is evidence that militants based in Pakistan's tribal region planned the assassination attempt. But Saleh said he had no proof the Pakistani government was involved.

Saleh told Afghanistan's Parliament Tuesday he knew of the plot to murder President Karzai and had warned the Afghan leader and his security advisor.
