Reporting from Kabul, Afghanistan -- Security for Westerners in Afghanistan took a sharp turn for the worse Saturday when an Afghan security guard working for the international shipping firm DHL shot dead the company's top two executives in the country before killing himself, authorities said.The early-morning attack, which killed a Briton and a South African, was as symbolic as it was bloody. It targeted a major multinational corporation at a time when Afghanistan is hungry for foreign investment. And it took place in a prosperous district in the heart of the city even as Western military officials are trying to calm fears that Islamic militants are tightening a noose around the capital.
