Kabul: Six American soldiers have been killed in a wave of Taliban attacks and bomb explosions this weekend in some of Afghanistan`s most volatile regions, NATO said on Sunday.
Three soldiers were killed fighting insurgents in two separate battles in eastern parts of the country on Saturday, the alliance`s International Security Assistance Force (ISAF) said in a statement.
Two other troopers lost their lives in an improvised bomb attack in the country`s south on the same day, the force said. And a sixth American died in another battle in the south on Sunday, it said.
The statements did not reveal the nationalities of the casualties but a military spokesman said that "all were Americans".
The troops became the latest in an escalating toll of ISAF casualties as the alliance fights a Taliban insurgency which had become increasingly deadly since the militants were ousted from power by the US in late 2001.
The number of the foreign troops killed in Afghanistan so far this year, with the latest deaths, has reached 471, compared with 521 who died during the whole of 2009, according to a tally based on that of www.icasualties.org.
