A soldier with the NATO-led International Security Assistance Force (ISAF) was killed Thursday, bringing to two the number of the military alliance casualties over the past two days, Xinhua reported.
"An International Security Assistance Force service member died following an improvised explosive device (IED) attack in eastern Afghanistan today," a press release of ISAF said.
The nationality of the victim had not been revealed in the press release. "It is ISAF policy to defer casualty identification procedures to the relevant national authorities."
Another ISAF soldier was killed in similar attack in Afghanistan's restive southern region on Wednesday.
More than 660 NATO soldiers, most of them Americans, have been killed in Afghanistan since the beginning of this year.
Taliban militants have often attacked Afghan and NATO-led forces with IEDs and roadside bombs but the lethal weapons also inflict casualties on civilians.
