Afghan officials say seven people were killed in eastern Afghanistan Saturday when the vehicle they were driving hit a roadside bomb.
The blast occurred in the eastern province of Kunar near the Pakistani border. The victims were security guards working for a road construction company.
Authorities do not know who was behind the attacks. Taliban militants waging an insurgent campaign against the government in Kabul have been blamed for similar incidents in the past.
Also today, a suicide bomber blew himself up in an attempted attack in the western Farah province. Officials say there were no other casualties.
