A suicide car bomber attacked a convoy near the Afghan capital Saturday, wounding two foreigners and four Afghans, officials and witnesses said as eight police officers died in an ambush by suspected Taliban insurgents elsewhere in the country, according to AP. In other violence, suspected Taliban insurgents killed two Afghans guarding a NATO logistics convoy, authorities said. The suicide attacker rammed his vehicle into a convoy of two four-wheel drive Landcruisers traveling on a main road leading out of Kabul, said Ali Shah Paktaiwal, chief of criminal investigations in the city. At least one of the vehicles was badly damaged, witnesses said. «I saw two bleeding foreigners being carried into cars and taken to hospital,» an unidentified witness told a local TV station. Zemerai Bashary, a spokesman for the interior ministry, said two foreigners and four Afghans were wounded in the attack. He said he did not know the extent of their injuries, or the nationality of the foreigners. It was also not immediately clear who the foreigners and Afghans worked for. Some of the injured Afghans were bystanders, Bashary said. British and U.S. forces prevented reporters from getting near the scene of the attack. Insurgent attacks on Afghan security forces or western troops are running at their highest level since U.S. forces invaded the country in 2001 to oust the hard-line Islamic Taliban rulers, who had harbored al-Qaida leaders following the attacks on the United States on Sept. 11, 2001. Most of the bloodshed has taken place in southern or eastern Afghanistan where the Taliban have historically been strongest, but there have been occasional suicide attacks in Kabul. Elsewhere on Saturday, insurgents detonated a bomb as a police patrol passed down a road in southern Kandahar province before attacking with automatic weapons and rocket propelled grenades, said police officer Umar Khan. Eight officers were killed and one was missing, he said. Also in Kandahar, a roadside bomb killed two Afghans guarding a convoy carrying supplies for NATO-led forces, said provincial police chief Sayed Aqa Saqib. In neighboring Helmand, Afghan soldiers shot and killed two suspected Taliban fighters as they attempted to plant a roadside bomb, said police officer Ghulam Wali. On Friday, insurgents attacked a police patrol in eastern Paktika, sparking a gunbattle that killed six militants and one officer, the interior ministry said in a statement. It gave no more details.
