Kabul - Two Afghan security guards were killed on Thursday when a suicide bomber targeted a US Army base in eastern Afghanistan, officials said.
The car bomber tried to enter the base in Gardez, capital of Paktiya province, but failed, an official with NATO-led International Security Assistance Force (ISAF) said.
He blew himself up in front of the base, said Rohullah Samoon, spokesman for the governor of Paktiya, a province that borders the volatile tribal regions of Pakistan.
Seven guards were injured, Samoon said.
The Afghan guards were employed by a local security company.
No Afghan or international troops were hurt, the ISAF official said. - Sapa-dpa
