The US-led military alliance said two of the soldiers were killed in the south and one was killed in the east. The other three soldiers were killed on Thursday also in the south.
NATO has not disclosed the identities of the soldiers.
The latest deaths bring the number of slain foreign soldiers to more than 622 so far this year. The year 2010 has become the deadliest year for the US-led foreign forces since the invasion of Afghanistan in 2001.
As the security situation continues to deteriorate in Afghanistan, US-led forces are killed by Taliban militants on a near-daily basis.
According to official figures, more than 2,100 US-led soldiers have been killed in Afghanistan since the US-led invasion of the country.
Figures released by Afghanistan’s Baakhtar News Agency, however, put the death toll at near 4,500.
Western public opinion is growing increasingly tired of the war and mounting casualties. The United States and NATO have more than 150,000 troops in the war-torn country.
The developments come at a time when the US and its allies have stepped up a bombing campaign in troubled southern Afghanistan.
Tens of thousands of Afghan and foreign troops have been fighting the Taliban in Kandahar Province to flush militants out of the region.
US-led foreign forces have been criticized for military operations, which have led to death and destruction in war-ravaged Afghanistan.
A human rights group says civilian casualties have spiked since operations started in Kandahar in early September.
The Afghan Rights Monitor (ARM) says the US-led campaign in Kandahar has destroyed or damaged hundreds of houses.
ARM says US-led NATO forces have used aerial bombings, hidden booby traps and mines in private homes.
According to the rights group, most of the attacks have been carried out in areas that hold about one-third of Kandahar Province’s population.
More than 100,000 Afghans have been killed since the US-led invasion of the country in 2001.
The loss of civilian lives at the hand of foreign forces has led to a dramatic increase in anti-American sentiments in Afghanistan.
