阿富汗首都自杀爆炸两死五伤

A suicide bombing near a NATO base in Afghanistan's capital has killed two Afghan security guards and wounded five civilians.

Officials said Wednesday's attack involved two men wearing suicide vests, and that at least one of them detonated their explosives after being shot at by Afghan security forces. 

The blast hit an area near Camp Eggers in a section of Kabul that houses NATO coalition headquarters as well as foreign embassies.  The attack, claimed by the Taliban, prompted alarms at the U.S. Embassy.

NATO said the blast damaged one of its vehicles, but that there were no reports of casualties among coalition troops.
