KABUL, Afghanistan (CNN) -- Two soldiers with the NATO-led international force and a civilian interpreter were killed Tuesday when a bomb exploded while they were on patrol in eastern Afghanistan, officials said.
The blast in the Ghazni province killed one soldier and the interpreter at the scene and wounded two other soldiers, one of whom died at a hospital, NATO's International Security Assistance Force said.
The organization did not disclose the soldiers' nationalities or details of the attack.
The security force is an alliance of about 40 nations charged with supporting the Afghan government in maintaining security.
Ghazni is one of 34 provinces in Afghanistan. In recent months, troops have been battling Islamic militants there.
Last month, Poland announced its soldiers, as part of the NATO force, were taking over security responsibilities in the province.
