Roadside bomb kills seven NATO troops in Afghan south

KABUL - Seven members of the NATO-led International Security Assistance Force (ISAF) were killed by a roadside bomb in southern Afghanistan on Thursday, the coalition said, the worst single incident involving foreign troops in a month.
ISAF did not identify the nationalities of those killed, although US, British and Canadian troops make up the bulk of the foreign force in the south. Almost 200 foreign troops have been killed in Afghanistan so far this year.
