KANDAHAR, Afghanistan - Four Afghan employees of a US-owned private security firm were killed in a suicide attack near a base housing thousands of international troops on Sunday, police said. The attacker, carrying explosives on a motorbike, targeted a US Protection and Investigations (USPI) vehicle just a few hundred yards from Kandahar airfield, a base for the NATO-led International Security Assistance Force.“There was a suicide attack against a vehicle of the USPI. Three guards and a driver were killed and another guard was injured,” a police officer at a nearby checkpost told AFP.
The bombing in this volatile southern city was the second suicide attack in as many days after eight people, mostly police, were killed in a blast in the eastern city of Khost.
