Separate Taliban attacks and bomb explosions have left six American soldiers dead in Afghanistan's most volatile regions, NATO has reported.
Three soldiers were killed while they were fighting insurgents in two separate battles in eastern parts of Afghanistan on Saturday, the International Security Assistance Force (ISAF) said in a statement, Press TV reported.
Two other soldiers lost their lives in an improvised bomb attack in the country's south on the same day, while a sixth American was killed in still another battle in the south on Sunday, ISAF said.
The statements did not reveal the nationalities of the casualties but a military spokesman said that "all were Americans," AFP reported.
The latest deaths bring the toll among the US-led forces in Afghanistan to 471 for the first half of 2010.
The incidents come as the number of attacks against Western troops in Afghanistan has soared significantly in the past months amid a public outcry against the prolonged war.
