At least two US-led foreign soldiers have been killed in separate Afghan attacks in the south of the war-ravaged country over the past two days, NATO sources say.
One of the troopers was killed in a militant attack in southern Afghanistan on Sunday, the sources said without providing more details.
This is while the other US-led foreign soldier was killed following a roadside bomb explosion in the same region on Saturday.
The exact location of the incidents or the nationalities of the slain troopers have not been disclosed.
According to the independent website, icasualties.org, some 227 foreign soldiers, including 165 American troops, have lost their lives in Afghanistan this year.
A total of 566 US-led forces died in Afghanistan in 2011. However, 2010 still remains the deadliest year for foreign military casualties, with a death toll of 711.
The high number of military casualties in Afghanistan has intensified opposition in the United States and other NATO member states to the US-led war in the violence-scarred country, undermining public support for the Afghan war. .
The US-led invasion of Afghanistan took place in 2001. The offensive removed the Taliban from power, but insecurity continues to rise across Afghanistan despite the presence of thousands of US-led troops there.
