A car carrying a Czech diplomat came under fire south of the Afghan capital on Tuesday, and two diplomatic guards were injured, Czech Foreign Ministry said. The Czech charge d'affaires, Filip Velach, was not hurt in the daytime incident, which occurred about 100 kilometers south of Kabul. It was not clear who opened fire or why. After the shooting, Velach and the two Czech police guards hid in a nearby house until they were rescued by a helicopter from the NATO-led international force in Afghanistan, Opletalova said. The two guards - part of a special police force that guards the Czech Embassy in Kabul - were lightly injured.
