NATO officials say the blast, which could be the result of an improvised explosive device, occurred in the country's south. Six Canadian solders and their Afghan interpreter were killed in the blast. It's the deadliest attack against foreign troops in Afghanistan since May.

    Afghan and NATO forces clashed with Taliban militants in Zhari earlier this week, leaving 33 suspected insurgents dead on Tuesday. Over 100 foreign soldiers have been killed in the country this year.
