Roadside bombs killed eight members of the international force in Afghanistan -- including seven U.S. troops -- raising to more than a dozen the number who have died in the previous three days, NATO said Tuesday.
The spike in deaths in the three days through Monday came as President Hamid Karzai again publicly raised doubts about the U.S. strategy in the war, saying success cannot be achieved until more Afghans are in the front lines and insurgent sanctuaries in Pakistan are shut down.
NATO gave no details of the Monday blasts except that they occurred in the south, the main theater of the conflict, and that five were killed in a single blast. The nationality of the eighth casualty, announced early Tuesday, was not given.
