KABUL (Reuters) - Eight U.S. service members working for the NATO-led force and one Afghan civilian were killed in multiple bomb attacks in southern Afghanistan on Tuesday, the alliance said in a statement.

The NATO-led International Security Assistance Force (ISAF) said several troops were also wounded in the “multiple complex (bomb) attacks” but would not give further details of the attacks, which come a day after 11 U.S. troops were killed in two helicopter crashes.
