Roadside bomb kills NATO soldier in Afghanistan

(AP) The international military coalition in Afghanistan says one of its service members was killed by a roadside bomb in the country's south.

The death brought the number of international troops killed on Thursday to eight.

Seven American service members died earlier in the day in a Black Hawk helicopter crash in southern Afghanistan. The Taliban claimed to have shot down the helicopter but U.S. officials have cast doubt on that and said an investigation is ongoing.

The U.S.-led NATO coalition did not release the nationality of the service member killed in the roadside blast..

Taliban insurgents have been waging a summer campaign against coalition forces and Afghan army and police being trained to take over full security responsibility by 2014.
