Suspected Taliban militants ambushed and killed six Afghans Thursday as they were transporting the body of a government engineer killed a day earlier in another deadly rebel attack, officials said. Thursday's victims were driving on the main highway linking the national capital, Kabul, with the southern city of Kandahar when they were attacked in Zabul province's Shahjoy district, said Ali Khail, provincial government spokesman. Initial reports suggested the victims had been working for an international aid group and that seven people had died, but Khail said only six were killed. He said he was waiting for confirmation of their identities, according to a report of The Associated Press.
