A soldier with NATO-led forces killed died Sunday as a roadside bomb went off in south Afghanistan, a press release of the alliance said.

"An International Security Assistance Force service member died following an Improvised Explosive Device (IED) attack in southern Afghanistan today," the press release added.

However, it did not identify the nationality of the victim, saying it is ISAF policy to defer casualty identification procedures to the relevant national authorities.

Taliban militants often use IED as roadside lethal bomb and plant it on the raods to target Afghan and NATO-led forces based in Afghanistan.

More than 590 NATO soldiers with majority of them Americans have been killed so far this year in Afghanistan.
